An optimized version of @theo_from_tinkertv optimization of @MarB's “Gridfinity tweezers box”. I didn't like having to store my curved tweezers with the pointy side up so I added a trough to allow them to be stored pointy side down. I also shortened the slot walls to allow easier access to tweezers of different lengths.
Unfortunately, this version doesn't allow stacking as it was necessary to accommodate all of my tweezers. A version could be made based on a taller bin to allow stacking.
The author remixed this model.
