Recently embraced the Gridfinity craze to organize my desk drawers. I couldn't find a holder for my spare Logitech M310 mouse…so I made one. Took the great SCAD file by @Jamie and made a template, then cut away the bits that I needed to.
It doesn't have magnet holes since I don't use them.
Printed in Elegoo Gray PLA. .28 layer height though just about anything should work.
The author remixed this model.
Used this fantastic SCAD file to generate a solid and then cut away the bits I needed to.
