Summary

I was trying to use some printed 18650 spacers, but they were not optimal. The original injected molded design has 2 of the same tabs per side, and that makes the printed counterpart weaker so this module has:

Bigger tabs, alternated ones
Looser battery fit
Perfect fit for nickel metal grids

Other Issues:Batteries are a bit loose in the holder, but it's fine. The parts didn't snap in place for me though so it doesn't hold everything together. Also don't like that there's so much space between the cells.

maybe a little too loose, they constantly fall apart while trying to set up, i am sure they'll be fine once nickle strips are holiding the cells together, just a little irritating

maybe try at 99% size? for me they were extremely tight, had to hammer them
