Gecko Splint - support for A2 pulley injury / finger ligament sprain from bouldering or rock climbing

prusaprinters

I designed this to support my A2 pulley ligament after a bouldering injury. I do a lot of typing in my day job and this enabled me to continue working while the ligament healedThis model is freely adjustable and doesn't compress the nerves and arteries on the sides of the finger. I tried the C-shaped splint described by Schneeberger and sold on Amazon but found it difficult to get the tension right to avoid pinchingHere’s some background information on pulley injuries from a medical doctor: https://theclimbingdoctor.com/pulley-injuries-explained-part-1/Hardware:Requires a stainless M3 machine screw and nut, somewhere between 12 and 24mm depending on sizeFilament and print settings:Don't use carbon fiber or glass filled materialsPrint in the default orientationRandom seams add a bit of texture and ventilationCustom sizing:Files are provided for finger widths between 12 and 20 mmIf you have Fusion360 you can change the “finger_width” and “finger_height” parameters as appropriateLeave a comment if you need a different size or have problems with scalingIf you aren't able to print this yourself I offer it for sale on Etsy at a nominal price:https://www.etsy.com/listing/1540426252/gecko-splint-finger-splint-to-support-a2
