Inspired by the honeycomb box. They have the same height as the small box from Honeycomb box but they have a slightly bigger footprint to fit the cells. As shown in the picture, you can still put one next to a bigger box. I haven't tried placing 2 next to one another but I don't think they will fit properly.

The CR2032 is the one I used but you can print the CR2035 and any other cells with a smaller height will fit.

I printed the casing upright on the thinner side and the drawer on the flat side without support or brim.
