This is a 2x3x4 Gridfinity bin to store a Helor 101 hand grinder. As my drawer is quite tall I chose to stand the grinder upright (rather than laying flat), because this way it has a smaller footprint. Stackability was (quite clearly) not a concern.

As the handle is round it would tip to either side if not stabilized, which is what the arm is for. 

The tolerances worked out great on my P1S, but depending on your setup you might need to adjust the slot size for the handle so that you can smoothly take it out without lifting up the bin. I have found that taking out the handle first and then the body of the grinder prevents this anyway though, because the body is so heavy. 

A step file for adjustments (tolerances, magnets, etc.) is included. The solid Gridfinity bin is based on the great collection of models by scheff.
