Hey, yeah, espacially the clamb Adapters are a bit weak and tend to lose the spool. On the other side they're a more quick and dirty solution wich will also do the work, but i needed a more stable Design. Thats kinda strange because my Bambu Studio is also running on Version 1.7.7.89 - but i'll dig into this to find the problem or better the solution... :o)

Yup, your screw-together design seems far more robust. It's not like it's using much more material to do it this way, either. There's the core on one half that goes down the middle of the spool and the other screw-on part on plate 1, but it feels like the bulk of the material goes into the body of the spool itself, and that's something that needs to be printed regardless of how the mechanism that holds the spool in the adaptor. How weird. I wonder if it's something Bambu are doing on their end to postprocess uploaded 3mfs? Great, now I need to go make sure that the one model I've uploaded so far doesn't suffer from the same thing... In the meantime, plate 2 printed just fine with the standard settings for PLA on my X1C gooping onto a textured PEI plate. I've had this just over a week now and I'm just astounded how well this all works - I'm coming from years with a Monoprice Mini, and this still feels like alien technology. One other thing I noticed - the GUI suggests that after slicing plate 1, the spool overlaps the area where the initial wipe of material is done on the top-right of the bed. I'm not sure if this is actually the case, but I'm printing this plate with the pair of parts rotated 180 degrees, shuffled forward a little in y and then the screw-on part pushed over a little so it doesn't intrude. I'm not sure whether this is for real or not. Like I said, I'm still fairly new to Bambu's printers and slicer, and I know that it definitely warns if you place a part that oversteps certain boundaries. Perhaps the slicer is smart enough to know not to do the wipe if a part is to be laid down in that area, but I'm planning on kicking this off and then walking away for a bit, so I didn't want to burn through 100g of filament just to find that it went exactly as shown and the wipe was now a piece of the part. :)

This is a very strange problem. If im using my generated .3mf file from my Desktop, no problem but if i try to open the exact same file from Makerworld, i get the same error like u. I'll reupload the File to Makerworld, maybe that helps... Happy to hear that your Prints getting done without issues. The Overlap might happen due to the fact that you're using a X1C while im using a P1S. My P1S doesn't do the Flow Calibration scan and because of that, i have more printing space.

Thanks for your feedback. The print looks fantastic! I'm happy it worked well for you, and it's good to know that other manufacturers also use this spool design. Honestly, during the design process, I thought about placing holes... but since I NEVER use them myself as I don't want to bend my filament too much, I left them out and designed the spool to fit the clips I use for all my filament rolls (like i said in the description) :) If it's important to you, I'd be happy to provide a design with holes again ;)

Clips did come to mind this morning when I finished the print. It must have been too late last night or early this morning and missed your comment about the clips🤦‍♀️. I just need to print some. I have at least 15 rolls of Amolen that are starting to age so I plan on printing a few more of your adapters so I can have those little rolls ready to rock n roll at a moment's notice. Again, nice work and appreciate the thought put into your design.

I measured the outside diameter of the upper part that fits into the center of the spool and it came out to 79.5mm, but the inside of the spool is closer to 76mm. Maybe they changed the spools.

Hey Taven, Amolen seem to switch the spools quiet often...We now can count 3 different Amolen Spools but the other two designs still fit the Adapter by removing one pin on each side. Looks like we have to Adjust the Adapter a bit for your Spools. Tell me what Measurements you need for the Pins, then i can make you a fitting design. I already change the outer Diameter of the Top Part. If you tell me the needed changes for the Pins, i'll send you the adjusted Design :)

Thank you so much for the 5-star rating! I'm genuinely pleased that the model was helpful, and the print went smoothly :)

Happy to hear that you like it. It's good to know that Amolen uses different designs for their 200g spools. Fortunately, I haven't encountered that issue, but you've found a very pragmatic solution. I hope it can help other users as well :) Thanks for your feedback!

I'm very happy that you're satisfied and thank you for the 5-Star rating! :) Print looks very nice!

Looks great! Happy that you’re satisfied with the model and thank you so much for your rating :)

Thanks for your 5-Star rating! Your print look good and I’m happy that you are satisfied :)

Thanks for your feedback! In the design process I thought it is better to be completely flush but you’re totally right, that makes it a bit harder to wind the screw. This spacer is a great Idea! If u need a screw with a build in spacer, let me know and I‘ll do my best to provide you one :)

Happy to hear that you print went great! I'm curious if you're happy with the end result :)

Yeah, I’m happy with it. It fits the spools well. It took a little pressure to get the tabs to snap into the holes on the roll at first but you want it to be snug. I wonder if it would be ok at 10% infill, just to save a little time and filament. I’ll be making more since I have several of these rolls. it printed pretty cleanly. There were a few stray runs of filament inside the cylinder for some reason. Not sure if it’s something with the file or if it’s something I didn’t do right in the slicer. I’m still getting acquainted with bambu studio after only using cura and prusa slicers.

Everything fits very well for me, but scrolling through the comments here quickly reveals that this type of spool seems to vary significantly. Stringing as well as shrinking of the holes can, of course, also be influenced by the filament used—I used Bambulab filament and the settings saved in the .3mf file. No stringing, no shrinking. 10% should be sufficient since there are no lateral forces, but how well it prints with 10% also depends on your infill pattern.
