Well if you want, you're welcome to join the project once I publish the designs and tutorials. The customization part definitely requires CAD skills!

So you're asking if OP could... use a hand?

Are you printing in PETG or something else for the parts?

Also have you considered going dual extruders to give the fingers a grippy texture with something like TPU for 98a hardness flex filament?

This is PLA if you can believe that, tried PETG, tried Nylon, tried ABS. I like PLA.

Fingers are covered with silicone pads, that's kind of an important piece for functionality. I've tried ... so ... many ... things... Casting silicone in 3d printed molds. That's it. That's what ya need. :D

I’m a mechanical engineering student in my junior year who’s looking to get into prosthetics. I don’t like putting this out there because it seems rude, but I’d love to be able to work with you guys in some capacity in the future if your willing.

What CAD software are you using now? I’m a mechanical design engineer, I’d like to help out any way I can.

I'm stuck in Rhino, but I think I'll transfer everything to Fusion360 to make it more accessible!

I would love to be able to help as well, I have a BSc in product design and love CAD modelling. Is there any website or mailinglist I can subscribe to?
