Knick's Prosthetic Finger v3.5.5This is not my own design, I just re-created it to allow other users to modify it as required.You can download for free the 3D printing files from the following sites:https://www.thingiverse.com/knick/designshttps://www.thingiverse.com/thing:904304Notes:Print items slowly and at best accuracy your printer can, it's worth it to get things fitting together best. I use Simplify3D, and generally print everything with supports, 0.1mm layers, 80% infill, 4 layers on top and bottom, 3 on sides, at 20mm/s. I've started to print sockets with thicker layers and a .6mm nozzle, which is much faster. For the moving parts where accuracy is more important, I use a .3mm nozzle and 0.1 to 0.15 layers.Material:I use PLA for the hard items - the two knuckles, middle section, and linkage. In this example, I used http://www.amazon.com/gp/product/B00GTY3Z9EUse something flexible for the socket, tip cover, hinge plugs, and bumper. In this case I used elastic TPU: http://www.amazon.com/gp/product/B00TI3JUSIAnother good option is Ninjaflex: http://www.amazon.com/gp/product/B00HSEWKSQ
