A holder that's 4x2x4 gridfinity units to fit my tweezers. I've seen most electronics tweezers seem to be 10mm wide at the handle, so they should fit here. I wanted my model to have a groove at the tip to allow for angled tweezers without storing them pointy tip up. I also added a groove at the bottom so you can just press on a tweezer's handle to lift it up, in case you're having a hard time picking them up otherwise. The model is stackable, which some of the other models here wouldn't allow. The height could probably be reduced to 3 units, but not below that. Let me know if you'd be interested in a shorter version.

The gridfinity template this was made with was generated with gridfinity-rebuilt-openscad.
