I'm trying to get my drawers in order and I took this chance to exercize myself in Fusion. So I used the uber handy collection of filled-in Gridfinity bins by jdegs, took my caliper, and got to it.

This is a 2u high bin for 8 LR43 that you can stack (my case is a 4u high, so I stack 2 units so I store 16 LR43 on 1x1).

It works great for me, I hope it will work great for you too. If you need a variant of this, feel free to remix it or ask me.
