21700 3p Cell Holders

A 21700 cell holder I came up with for make a 3p battery setup. They nest together in a nice, compact hexagonal/staggered shape for efficient use of space.

There are two variants, and two setups. The first is a single piece, you can arrange these in shapes as you please. The second one is a 3x2 set. I used this to make the battery a "solid block" by offsetting them from each other. The two other variants are just to fill up a Prusa sized bed.
