Parametric Finger Splint / Support

I dropped a chunk of concrete on my finger a while ago, which crushed it in a spectacularly painful way. I didn't want to go to a clinic just to be told to support it and avoid using the finger until it healed (there's not much you can do for a fingertip, even if it's broken). I had other splints on hand, but they all had a fatal flaw - you can't type with them due to their bulk. Clearly I needed a better solution.

Putting pressure on the tip of my finger caused the most pain, and I was massively behind on my paperwork. I needed to be able to type! So I designed this splint to move the pressure of typing to the next joint down, keeping pressure off the fingertip while also immobilizing it. Creating the first revision was painful, but once I had a rudimentary support the following iterations were much easier.

It's constructed with hulled circles and spheres, offset by a few millimeters to account for the ovoid shape of a finger. The angle between the first and second joint is cust
