Gridfinity Label Tape Bin

This design may be better or worse than this one, depending on your needs.

Gridfinity bins for storing Brother labelmaker-compatible label tape cartridges. 

2xN bins are for vertical storage, 3xN bins are for horizontal storage in case your drawer isn't tall enough to store them vertically.

All bins are 3u tall, stackable when empty.

Cartridges per bin:

Nx1: 2 cartridges

Nx2: 4 cartridges

Nx3: 6 cartridges

Nx4: 9 cartridges
