This model is necessary for 3D printing a transparent resin shell for the Ploopy Thumb trackball, as seen in my YouTube video.
The increased bridge thickness on the buttons reduce the likelihood of print failing.
All the other files were unchanged and downloaded from the Ploopy github, including the LittleButtons.STL which I've left unmodified and printed with no issues.
Seen in the photo: Assembled Ploopy Thumb, printed in transparent UTR-8100 resin at PCBWay.
I don't recommend doing this for a daily used Ploopy Thumb. Assembly can be difficult and the weight of the buttons in printed resin is not optimal.

Increased thickness of all flexible bridges to 1mm
