3D model description

A trainer for fingers extension.
Contains 2 types of rings: a bigger one for 4 fingers besides pinky and small ring for a pinky.
Ring have a hook via which you attach it to an office rubber band (or 2 depending on resistance you want).
Bigger ring has a radius of 9mm and a small one has a radius of 7.5 mm. If your fingers are bigger - feel free to scale it up. However if you have a smaller fingers, I'd suggest to change the inner radius of ring by reeeling some tape on it (isolation tape/climing tape), since due to scaling down the hooks size will get smaler too and you'll struggle with putting a rubber band through it.

The end result of assembly is shown on a picture.

3D printing settings

Any layer thickness depending on how smooth you want them to be. From my perspective it doesn't make much difference. Fill density can be easily set to 100, the parts are not that big.
