I have (poorly) remixed the nosmarb beard trimmer to make a 1x1 gridfinity holder for the beard trimmer. Note that the beard trimmer takes more than 42x42mm size of the gridfinity tile and requires clearance, look at the photos to have an idea.

The original bin has a 9u size when empty.

This is my first ever 3D model uploaded and I have my first 3D printer, so this is a very improvised model, I may update in the future if I really begin to learn how to use 3D modelling software for manufacturing.
