A2 pulley, Annular ligament brace, ring

Was designed to fit my ring finger. The inside can be covered with a piece of tape to make it more comfortable. There are numbered, different sized clips to adapt to your finger. It might also be possible to scale the model up or down for a better fit. My finger is about 14mm-15mm thick when slightly compressing it with about the force the brace should exert. The brace itself is 17,2mm wide when not compressed with a clip. This leaves enough room to put a layer of tape on the brace, which I recommend doing.

The ring is shaped to leave space on either side of the finger to allow for normal blood circulation.

The ring is designed after instructions I found online. Especially a set of instructions by a hospital in Switzerland called Balgrist. They also provide a nice instructions for therapy and avoidance of injury.

It's probably best to see a doctor before using this.
