Gridfinity 18650 battery bin generator
A Gridfinity bin for 18650 or 21700 lithium cells standing up, one round pocket each. Say how many along and how many rows.
How to make yours
- Set the cell's diameter; each pocket is 0.6 mm wider so it drops in.
- Set how many cells along and how many rows; the bin grows one 42 mm square at a time to hold them.
- Set how deep each pocket is, and tick on magnet holes if your baseplate has magnets.
- Download it as STL, 3MF or STEP, and print it.
