Self Closing Hinge Adapter

The model is intended as inspiration and a proof of concept, not as a direct print. The design allows quick mounting and removal without tools, and it leaves no traces behind.

Unfortunately, I cannot find the same spring model for sale. I only have two, salvaged from industrial equipment. However, you can use any torsion spring you have on hand, as long as it is stiff enough and of good quality.

I will try to make the Fusion model as parametric as possible so you can adapt it to your needs.

The diameter of the hinge body is 15 mm, and the pin to the door is 8 mm. You need substantial space between the hinge and the door frame. In my case, I had 3.5 mm, so the adapter has plenty of room with a shell thickness of 2.5 mm. The adapter cap is held with superglue through the center part and four pins made simply from pieces of PLA filament. You can use whatever you prefer, or try it without the pins.

If someone needs help, just send me a message.
