This 4x4 Gridfinity device holder has sliding dividers to hold your drives, battery packs, or whatever you want.
There are 2 types of dividers, the loose one has a little more play while the regular divider is a tighter fit. Both types of dividers can be held in place with a 3x8mm screw.
I've printed these in PLA with a 0.6 nozzle. The regular fit divider needs a little trimming if you have some elephant foot going on in the first layer, but it's just a little nip with some flush cutters. No supports are needed.
