Magnet Dispenser for 3D Prints: Simplify Magnet Insertion with Precision
The Magnet Dispenser Tool is expertly designed to streamline the insertion of magnets into 3D prints. This tool not only speeds the process of inserting magnets into 3D Prints, it also ensures correct orientation and secure fitting, making it ideal for projects that require precise magnet placement.
Key Features
Dual Dispensers for Perfect Alignment
- Includes two dispensers for each magnet size – one for north-up and one for south-up orientations
- Use different colors (e.g., red for north-up and blue for south-up) to help easily identify the dispenser's orientation
- Eliminates the hassle of misaligned magnets
Design and Utility
- Developed after extensive refinement
- Allows for friction-fit insertion and is also suitable for magnets that are glued
- Tapered tip facilitates use in tight spaces
Ease of Use
- The dispensers are designed to accommodate the specified magnet sizes for their internal holding magnets, but can dispense magnets of any thicknesses for the specified diameter. For example, for the 6x3mm dispenser, you will need 6x3mm magnets to assemble the dispenser, but once assembled, that dispenser can dispense any 6mm diameter magnet such as 6x1, 6x2, 6x3, 6x5, etc.
Convenience and Storage
- Features a snap-on cap with an embedded magnet and a top slider magnet
- Ensures secure storage and prevents accidental magnet spillage
Customization and Printability
- No supports needed for printing
- STL and STEP files included for personal customization
- Compatible with PETG, PLA, ASA, ABS, etc
- Adjust x/y hole compensation if needed for perfect fit
Visual Guide
- Fusion 360 images provided for easy assembly and understanding of the internal mechanism
Use the Magnet Dispenser for a hassle-free, precise, and efficient magnet insertion experience in your 3D printing projects.
Supported Magnet Sizes
Dispensers are now provided for the following magnet sizes as of Version 5
- 2x1mm
- 2x2mm
- 2x3mm
- 3x1mm
- 3x2mm
- 3x3mm
- 4x1mm
- 4x2mm
- 4x3mm
- 5x1mm
- 5x2mm
- 5x3mm
- 6x2mm
- 6x3mm
- 7x2mm
- 7x3mm
- 8x2mm
- 8x3mm
- 8x4mm
- 9x2mm
- 9x3mm
- 10x1mm
- 10x2mm
- 10x3mm
- 12x2mm
- 12x3mm
- 15x2mm
- 15x3mm
- 20x2mm
- 20x3mm
NOTE 1: The 1mm magnet thickesses are just too thin to work reliably with the friction-fit of the slider and caps. Therefore, I have made the pockets of the “1mm” thickness magnet dispensers to be that of the 3mm variety so that they work. So to assemble a 1mm magnet thickness dispenser, you will need to purchase a few 3mm thick magnets to assemble the dispenser. A 2mm thickness will likely work ok, too. Note that the text on the dispenser will still say “D x 1 mm” for the barrel, “Dx1” on the cap, and “D/1” on the slider, so you know what magnets you have loaded into it.
NOTE 2: the above are the sizes needed to assemble the dispenser. The dispenser can still dispense any thickness of magnet as long as the diameter is the same. So if don't see your specific magnet thickness listed above, you can still print the correct diameter, assemble the dispenser with the correct magnet thickness, and dispense other thicknesses.
STEP and STL raw files are included if you do not wish to use the provided profile.
Quality Assurance Testing
- All dispenser sizes have been printed by me and extensively tested
- I have purchased all magnet sizes at significant expense to myself to ensure fit
- Magnet diameters are tricky for press-fit tolerance and controlled by no less that 5 Fusion 360 parameters that must be balanced to achieve good fit
- Multiple iterations of each dispenser were printed and refined
- Many kilograms of filament and hundreds of hours of print-time were consumed during this process
- All to ensure the best quality printing and fit-up for each dispenser size
About the Profiles
- Please use the “Designer” profile as it guarantees the latest files and version with all new magnet sizes and features. The Designer Profile will be listed at the top.
- NOTE: The “Designer” profile is a single profile that contains plates for all magnet sizes so far. Please ignore the “total time” reported by MakerWorld for the profile. You only need to print the plate(s) that you need. Each plate takes about 2.5-2.9 hours on my X1C using the included “PETG” profile which is slowed down for good PETG layer adhesion and quality.
- While the other profiles may be ok, their file / update version may be out of date. So if you want the latest sizes and model improvements, please choose the top “Designer” profile.
Accessories
Be sure and check out some nice accessories that other folks have created to work with these dispensers.
- Tip Caps - these are nice caps for the dispensor tip. Not only do they help keep the magnets contained within, but they also protect the tip. Additionally, they are labeled with the magnet size, which is nice. Thank you @onegotowned ! https://makerworld.com/en/models/149038#profileId-162633
- Vertical Workbench Stand - This is a very nice stand for select diamagers made by @nickramsey57. A number of folks have asked about stands / organizers for the dispensers, so this model will likely be useful to a number of folks. Thank you @nickramsey57 ! https://makerworld.com/en/models/206388#profileId-226561
- Vertical Workbench Stand (parametric) - Here is another very nice stand made by @RevHazlett. You can specify the dispenser sizes that you want it to hold and then generate, making it customizable to your needs and the common magnet sizes that you use. Thank you @RevHazlett! https://makerworld.com/en/models/435087#profileId-340031
Update History
Version 5: 2024-04-21
- Emboss the magnet size text on the Barrel (see photos), allowing one to view the size from the side, and also allowing one to print all of the barrels on a single plate and not get the barrels mixed up as to what size they are for.
- Include the magnet size text on the Slider (see photos), allowing one to print all of the sliders and caps together on one plate and not get the sliders mixed up as to what magnet size they are for. Also provides additional text identification of the magnet size within.
- Include 11 new magnet sizes:
- 3x1mm
- 4x1mm
- 5x1mm
- 7x2mm, 7x3mm
- 8x4mm
- 10x1mm
- 15x2mm, 15x3mm
- 20x2mm, 20x3mm
- Re-organize the plates so that they are a little easier to manage. All dispenser sizes for each “diameter” are spread across three plates now - the Barrels, the Red Caps and Sliders, and the Blue Caps and Sliders. This allows one to “print-by-layer” instead of “print-by-object”, and the text also comes out better. Additionally, it is now easier to construct a plate with all of the size variations on 3 individual plates and print them all at once.
Version 4: 2023-12-26
- Fixed an issue where the smaller diameter magnets such as the 2mm, 3mm, and possibly the 4mm magnet diameters could inadvertently slip through the vertical barrel slider stem slot. Prior to this update, the slider stem was a fixed 3mm + tolerance width. With Version 4, the slider slot is now dynamic based on the magnet diameter. So now, the smaller diameter magnets are captive within the barrel and cannot slip out inadvertently.
- Tighten up the tolerances between the “slider” and the “barrel” for a better fit and smoother operation.
- Use the Profile: “Version 4: All Sizes …” for the latest from this update.
Version 3: 2023-12-22
- Added additional magnet sizes
- 2x1mm, 2x2mm, 2x3mm
- 9x2mm, 9x3mm
- Text is now added within the Fusion 360 Model File, eliminating the need to add the text using Bambu Studio
- Ensures consistent text placement and easier colorizing of the text
- All plates are included for all magnet sizes, two dispensers per plate, print sequence: print-by-object
Version 2.1: 2023-11-28
- Added additional magnet sizes
- 3x2mm
- 4x2mm, 4x3mm
- 5x2mm, 5x3mm
- 6x2mm
- 8x2mm, 8x3mm
- 10x2mm, 10x3mm
- 12x2mm
- The magnet size text is included on the cap for easy identification - see photo
Version 2: 2023-11-20
Updated to “Version 2”. Significant updates an enhancements have been made, some seen, some unseen.
- Added additional magnet sizes
- 3x3mm
- 12x3mm
- Each magnet size is on its own plate, two dispensers per plate, print sequence: print-by-object
- Redesigned “thumb slider” for greater comfort and stronger press force
- Slider stem has been reinforced
- Many enhancements for smoother operation with internal chamfers and fillets, enhanced tolerances, and strengthening of key internal components

Nice design. Magnet size can easily be added to the cap in Studio.
Now we're waiting for remixes for 4, 8 and 10mm diameters :)

Wow - that looks great!
More diameters are coming soon. I did the 12mm yesterday, along with a redesigned slider that is easier on your thumb for when you really need to pressure-down on a tight press-fit - based on suggestion from @HackVector. I also beefed up the slider "stem" also to make sure it doesn't break if you really crank down on the new thumb lever.
I figured I'd do the largest (12mm) and the smallest (3mm) first, and if I could do those two, the others will be breeze.

Good ideas and a plan as well ! Will the internal magnets stay with 6x3 or will they be of the same size the dispenser contains? Maybe 12mm could be too strong then, whereas 6x3 seems to be the sweet spot …

From the perspective of the dispenser, it only cares about the diameter of its own internal "holding" magnets. It can dispense any thickness for a particular diameter. But I was thinking that if someone's "go-to" magnet is a 6x2mm, but the dispenser requires a 6x3mm, then they'd have to purchase some 6x3mm magnets and that would be pretty inconvenient.
So my plan is to do Dx3mm and Dx2mm for all of them, so we'll have (3, 4, 5, 6, 8, 10, 12) x (2, 3) variants.
I did get the 3x3mm working, along with the 12x3mm (and, of course, the 6x3mm of the original). So I don't expect any problems with the other sizes.
I do note that the diameters of the magnets as printed due to filament / hole tolerances change when you get to those small diameters like 3mm (super tight), and whether the hole is in the thin-walled slider or the thick-walled cap. If I size the hole correctly for the slider, it's too small in the cap. And if I size it correctly for the cap, the hole is too large in the slider. So, at least for the 3mm, I compromised and set the size somewhere in between. That makes it a very tight fit in the cap, and needing a drop of medium-viscosity super-glue for the slider holes. Just an observation. I didn't have any problems, but at least for the 3mm variation, assembling had the extra hassle of using superglue for the magnets instead of a nice, easy press-fit for the slider portion.
And yes, those bigger magnets are strong!
I've found that 6x3mm is indeed a sweet spot, also. It's my go-to for most things, which is why the original variant was 6x3.
Thanks for the kind comments and suggestions!

Thanks! Your print looks great!
I'm very close to publishing the other sizes. All of the additional sizes printed perfectly for me the first time except the 5x3mm. So I adjusted the magnet tolerances slightly and am reprinting to test.
I tried putting the text on the caps so folks didn't have to take the extra steps to do that, but the Text Tool is not cooperating for me. It's working for some caps, but not others. So I'm leaving that off for now.

@Brian Dean Yes I had similar issues with the text as well, when printed it screwed up the intial layers leaving holes etc.
Trying again on a few different methods - as permanent plastic is better than a Ptouch label :P

@OzDruiD yes for me I had them laid out as in the profile with blue and red caps and print-by-object. If the red cap printed first, it would work ok for that one, but when it switched to the blue cap, half of the bottom of the cap would be white like the lettering and the other half blue. So while one would work, the other wouldn't unless one separated into different plates, and for all the variations of this model, I just don't think that's feasible to have so many plates. Once I get the other sizes uploaded (probably today, I'm finishing up a few tweaks on the 10x2mm and 12x2mm sizes), there will be 14 plates, and possibly up to 20 plates if I do the 1mm thick variety. That would mean upwards of 60 plates and IMO, just too confusing.
If you can get that to work though, let me know how you did it. I.e., print-by-object with two barrels, two caps, and two sliders, and text on the bottom of the caps. It does increase the print-time a bit, but worth it, IMO.

Question on timing. I loaded up all the plates into my bambu studio and tried to do 10x3mm plate. Bambu studio was showing over 1 day to print. I removed one set and left only one in 2 colors and its currently printing under 3 hours. Why such a big time difference? screenshots of total print time attached

Hi @kalex1114 , if you used your own print profile instead of the one included, I think that may be the cause. I've set the "print sequence" to "print-by-object" instead of "print-by-layer". Print-by-object causes Bambu Studio to fully print an object before moving on to the next one, where as print-by-layer prints a single layer of all objects. If you still have it print-by-layer (the default for Bambu Studio), then it is going to try to switch filaments many times.
For print-by-object, it should only switch filaments a couple of times for the caps (for the text), and then finish the rest of the cap in whatever color you selected for them. But in print by layer, it will switch multiple times per layer.
At least that is what I suspect is happening.

Ok, I'm trying to help so I opened the profile from Makeworld, importing into Bambu Studio to ensure we are working from the exact same 3MF file and tried to simulate what you did.
I disabled one barrel - the same one you did, I think. And disable the "blue" cap and slider.
I get 3h17m, which seems about right. I'm really not sure why you're getting over a day to print. I've attached photos from the slider (prepare and preview).
So I'm not sure. Is it possible that print-by-object was somehow disabled on yours and it's printing by layer? How many filament swaps do you get? I'm getting 4 filament swaps on my test in trying to debug what might be going on.

Version 5 - All Sizes - 3 Plates Each, PETG
These thing are awesome! I stacked all the ones I wanted up on two plates - putting all the rods together got around minimum layer time and making assemblies of the two different polar color pieces did the whole thing in like five filament swaps. Less than six hours printing time using Bambu PETG Basic. Thank you for this model!
Liked them so much I made a parametric stand for them - https://makerworld.com/en/models/435087#profileId-340031

Thank you so much! When I'm printing a lot for testing I do the same thing and print all the barrels on a plate, all the red caps and sliders on another plate, and then all the blue caps and sliders on a third plate. And I set those plates to "print-by-layer" instead of print-by-object like I've done for the plates that have all of the components on a single plate. That way there are only a few filament switches.

Thank you. You're more than welcome to link it if you'd like. While it's fixed at a capacity of 2x6, the F3D is fully parametric so you can scale it to whatever sizes are desired.

Design makes the caps rather tight - I had to shave the lugs down a bit to get the caps on and off, particularly on the smaller tubes with less flex.

Glad it printed well, and wow, I love that base! @nickramsey57 , do you have that base uploaded? If so, I'd be happy to link to it from the Model page for the dispensers. A lot of folks have mentioned wanting a good base or holder for these and there are a lot of design possibilities, depending on what folks are after (gridfinity, hex-wall hanger, workbench (like yours) and similar. Please just let me know, I'm happy to link to your model and help folks out by being able to find it more easily.
Thanks for the photo and the great rating!
On lugs and cap fitment, you are correct that it's a little harder to put the cap on and remove it for the smaller sizes. That's mainly due to less flex in the cylinder wall for the smaller diameters. I did have a version earlier on that thinned out the wall near the top of the cylinder so it flexed more easily for the cap. However, I found that it either made the cap too easy to come off for the larger diameter tubes, or the lugs themselves could break off. I may still work on that, but fixing the one issue seemed to cause more and other issues, so I decided to leave the wall thickness near the top alone. I'll see what I can come up with - perhaps make that another "parameter" in my Fusion 360 model and have it dynamically thin-out the way near the top for more flex for the smaller-diameters-only.
Thank you for the feedback!

Version 5 - All Sizes - 3 Plates Each, PETG
On the first impression, I just wanted to try printing the 8x3mm tubes and everything was excellent in PLA, but printed slowly. I have printed 5 entire dispensers and I like them more and more xD
Have you considered designing some type of classifier to have them all arranged vertically? I saw that someone here made a kind of case by size.

Glad they turned out good - they do print a little slow for PLA mainly because the profile is for PETG. It does work fine for PLA but like you said, maybe a little slower than normal.
I have considered a container to organize them. I am currently working on such an item, but is more of a whole drawer and bay that will hopefully hold many in the vertical position inside the drawer. The main downside is that said drawer and bay does use a lot of filament and takes a long time to print. I'm currently using PLA+ for that during development and testing, and I think PLA+ will be fine, so I'll probably stick with it. I'll upload when I have it ready and update the description to point a link to it for folks that want to print it.
Thanks for the kind comment and great rating. Great photos, too! Thank you!

It would probably be more convenient if it were somewhat modular, so that everyone can print the size they use and there are no empty spaces, etc. I will be attentive to the development you make, I am interested!

Those look great, thank you for the photo!
Note - no scaling should be required. In the "Version 4 - All Sizes" profile, you should find 19 plates, each plate having a specific size. The sizes go from 2mm diameter to 12mm diameter, and varying thicknesses (mostly 2mm and 3mm thick).
Please double check - or re-download and get the latest profile. You should find all the available sizes ready-to-go without having to scale.
Additionally, that model is the "Version 1" model. The later model(s) have some nice improvements that I think you will appreciate, such as the size printed in the cap, new thumb slider that is more comfortable, stronger dispensing tip, and other nice features.
But great job sizing the V1 model for all those sizes! I'm sure that took some experimentation.

Those looks gorgeous, thanks for the photo!
What material did you use, if you don't mind my asking? I'm asking relating to the slider tolerance. In mine, printed in PETG, the slider slides freely, but is not "loose", i.e., very little to no side-to-side movement. I suppose I could tighten that up so that it requires some force to push it through the barrel, but may begin to "wedge" near the bottom where there's no give due to the fully enclosed bottom tip. Sorry you had to use tape, and thank you for the positive rating!

Silver is PLA basic and the rest is PLA-CF. It does slide freely, but has just the tiniest wiggle on the slider. Still works great, but I wanted to add just a small line of tape to keep it from sliding.
