MCP ring splint

thingiverse

This is an MCP brace for hypermobility in the first knuckle of the fingers. Video explanation: https://www.youtube.com/watch?v=ObN70mUm4xo I made these because I tend to hyperextend my fingers while typing. It doesn't hurt to do this once or twice, but after several hours of typing my hands can become pretty sore. This brace prevents fingers from hyperextending but does not limit normal range of motion. Similar braces must usually be custom ordered, and cost between $80-150 each without insurance. When 3d printed, these cost about 2 cents each. It's a fast print, and after a couple days of use my joint pain is basically gone! Since I made these for myself, I have included sizes that tend to fit my hands. The included sizes are: * 4 * 5 * 6 * 7 * 7.5 * 8 * 8.5 * 9 * 10 The models can be changed according to your needs pretty easily in Tinkercad. I have included a link to my model below. The long loop goes on the top of your hand, and the short loop goes on your palm. The longest loop should be long enough to go around your knuckle. The shorter loop should be short enough to allow your hand to close normally. A digital caliper will be very useful for taking these measurements. This is the first 3d thing I have modeled and used. Constructive criticism is very much welcome. This thing was made with Tinkercad.

In the meantime, here is a list of ring sizes. Provided sizes are US ring sizes. https://en.wikipedia.org/wiki/Ring_size
