Description

Hi,

I have created this concealed hinge that print in place.

There is one functional version, robust enough for real applications, and one version just to play with. (It is oddly satisfying).

EDIT 2024/02/25 : Fixed the toy version (bad versionning sorry). Built in supports will now work as intended

Please note that the files are LEFT side hinges. You will have to mirror the mechanism for a right side hinge.

In order to have a robust mechanism, the tolerance are quite thin.

After printing, you will have to force a little to free the model the first time.

(There are 8 little pillars around the arms which will break, it is normal. They are built-in supports)

The functional version contains 3 items : the mechanism and 2 trapezoids.

Mounting the hinge is very easy : One trapezoid is screwed in the door and the other one is screwed in the furniture.

The mechanism will then be pressfit on these.

Be carefull, the trapezoids have an orientation !

The figure below illustrate where you should screw the trapezoids.

EDIT : You can find in the link below, a model helping to drill holes at the right place. It includes a custom print in place caliper

The cinematic of the hinge allows up to 21mm of overlap.

You are free to inprove the design, you will find the sources here:

Maybe also design a guide piece with holes. Something you can align with edges of the cabinet / door and just drill 2 holes in the exact point. Easily repeatable holes and much quicker than measuring.

The designer has replied

@SigmaT4

It is a great idea ! I'll design that, unless you want to give it a try and upload it as a print profile. On the door side, it wont work because of the variable overlap length.

@HerrTankwart

Replying to @SigmaT4 :

For the doorside you can go with a device which is variable in length. How do I explain... Take two plates with longholes which match the overlap. This way you could measure the overlap and transfer the result to the device. Kinda like a caliper... I will draw it quickly with paint, but please don't judge the result :-D I think you get the idea, even if it's ugly ^^ EDIT: It's also just an quick idea, so there's a lot of room for improvement! The first thing which came to my mind while drawing, that one "slider" isn't enough, due to the fact that it is also turnable und you had to be sure that it's 90°, while marking the holes. A second cylinder should help or even better: boundaries around one of the parts, so it will always stay at 90°, just like a caliper. EDIT EDIT ^^: If it should be a "one-part", you could make a device that has marking_zones for every milimeter. I know this will get tight, but you can make it wider and shift the marking-areas... back to paint... image is coming soon ^^ If my english would be better, I wouldn't be forced to paint those crackly images ^^

(Edited)

@SigmaT4

Replying to @HerrTankwart :

I think the "two part" version is better as it will be easier to embed the 2 wholes needed to mark out the positions where you should drill. And its also a great excuse to make another print in place thing lol

honestly such a cool design and it specifically came in handy on the project Im currently working on! Thanks for the work and sharing. I used a boost for this model

The designer has replied

@SigmaT4

Clean print ! :) Thank you for the boost !

@Makanize

These printed easily and worked very well on an aracde I’m building for my kids. Thanks OP

The designer has replied

@SigmaT4

Nice workshop, and nice build ! The door looks massive, I'm impressed that 2 hinges were enough What filament is it ?

@Makanize

Replying to @SigmaT4 :

Thanks! the door is about 22” x 32” x 1/2” (56 x 82 x 1.2 cm ). I used Elegoo PLA+ off of Amazon. It did sag a little downward after installation but I just moved the top himges a little in and it works great.

Great model, a little stiff off the printer but very smooth and durable once loosened up

@HerrTankwart

Allow me one question: Is it intended that the one trapezoid in the "loose tolerance"-profile is pre-installed? This way the slicer gives back a solid instead of the slide-in-mechanism. I cut the model, removed the object and combined it back again. This way it prints support instead of the solid. Just like the standard-profile does. Maybe you should check this and change the profile. ;-) If I'm wrong... sorry! I haven't slept much this night :-)

The designer has replied

@SigmaT4

I might also lack sleep. It is a mistake. Thank you so much for pointing this out !

Was amazed how sturdy and workable

@noisersparco

how did you print it ? it not working to me ?

@jpdesigns

Replying to @noisersparco :

Just used the available file. If you don’t have a PETG printer, some of the files won’t work.

(Edited)

@noisersparco

Replying to @jpdesigns :

I tested it with PLA. I will try with PETG. Thank you for your advice.

@noisersparco

Hello. Can someone can explain to me how to print it ? I printed 3 times, 1 broke and the others are not moving.

The designer has replied

@SigmaT4

There is a version with "loose tolerance" if you have troubles. The first time, it is easier to stow the mechanism than to extend it. You should let the auto extrusion calibration run.

@noisersparco

Replying to @SigmaT4 :

Thank you for your help. I will try with the calibration.

@GlitchyCorgi

Printed the toy version twice with black bambu pla and both came out completely fused

The designer has replied

@SigmaT4

You must calibrate your filament extrusion (or use auto extrusion calibration) The tight tolerance is what makes the model usable for real application. (else you would have too much slack). Don't hesitate to force a lot on the mechanism to break it free. (the best way is to force the mechanism in the retracted position) There is a print profile easier to print but it will be less rigid

@SigmaT4

There was a versioning error in the upload files. The toy version was old and had not the built in supports. Sorry. You can try again

@jasonalvarado

This is awesome! I've got a project in mind. Any idea how much weigh this can hold? Planning an orientation where the front face will lift up.

The designer has replied

@SigmaT4

2 kg, at 35 cm from the axis is not a problem. 6 kg is too much
