Paremetric Fingers Version 2
Here are OpenSCAD scripts to create customized fingers for prosthetic hands. There is one file to create the proximal phalanges, one file to create a combined distal/intermediate phalanges, and an additional file to create extra pins (to go along with one of the possible, selectable options).
Each file includes a great number of possible customizations that can be selected or modified in the Parameters section of the files. For example, you can set a scale factor, a finger tab width, a finger joint length, standard knuckle size, variations from standard size, string size, bungee size, knuckle hole size, whether to use a pin in the proximal-intermediate joint, whether to use a tie-off or a standard hole for the bungee, whether to use minkowski to smooth the print or just skip it and do a quick render, and whether to include support on some parts to make for cleaner prints.
I have simplified the parts quite a bit from the initial version, so that they now render much faster. I have tried to include every useful option I can think of. If there is some option you wish was there, but that is not, let me know – maybe I will add it.
I have included a full set of sample .stl files the way that I like them for the hand I am currently making. Those are more examples than anything else. I am a big believer in taking the time to customize each finger to your own needs.
