R.A.T. 5 pinky board

thingiverse

This is a pinky rest for the R.AT. 5 mouse, designed by a user who loved the mouse but found it lacking that particular feature. The higher tier models did have it, but not as a separate item, so they decided to create it themselves as a fun exercise in 3D modeling. They printed an initial version which fit perfectly, but noticed some issues like misaligned holes and low positioning on the lower side. Corrections were made and a change log was added for version 5.2. The user has edited the part but has not yet printed it to test the changes. Printing instructions include using 0.1mm layers, flipping for the correct direction (board-side down), and adding support only on the outside.
