Keyboard tray edge/ wrist rest/ mouse pad clip holder

thingiverse

Extend it to whatever length you need in your slicer, but this clip will securely hold a slim gaming mousepad on a standard keyboard tray that's only 0.629 inches thick or 15.99 millimeters. It also makes for a fantastic wrist rest for your keyboard hand, far superior to a 90-degree wood edge. Print it with a brim and rotate it to print vertically.
