Problem: Every once in a while some guitar players will go out and party hard. Sometimes they may even injure their strumming hand. Also, some musicians may suffer from arthritis, or issues that make holding a standard guitar plectrum (aka pick).
Solution: An ergonomic Guitar Pick Grip designed to hold standard guitar picks.
This design uses standard guitar picks that are mounted into a custom handle using set screws. The picks can be easily replaced. Ideally, this would be fabricated out of metal, but that's just a ridiculously expensive concept that would cost hundreds of dollars each... so... it's also easily 3D printed out of ABS, PLA, or any other SLA/FDM processes.
Currently, the only issue with plastic is that the set screws tend to wear away the plastic threads after a several pick replacements. Oh... and it also depends on how Hard Core the musician is.
The design of the grip can be easily customized for larger and smaller hands. I think it would be a lot of fun to make one for a famous rock star one day. If you ever hear of a guitar player with an injury, please send them to me!
Modeled in Onshape. (Btw, if you use Solidworks, then go check out Onshape. Honestly, I will never use Solidworks again.)
The below images were rendered in Adobe Dimension.
(Note: I have been experimenting with Dimension, and it's got lots of potential. I believe that the visible faceting on some of the surfaces is due to an .STL file import limitation of Dimension. Once Adobe releases support for .STEP file imports, I think this may fix the issue.)
Below is a variation with a higher support angle that can work with a "thumb in a cast".
