18650 Battery Box 6 x 3 rows

This is a box for the battery holder https://www.thingiverse.com/thing:4387398/remixes

It is exactly for 6 x 3 rows, 155 x 74mm internal, 159 x 78 mm external.

There are 10mm spacing on the both sides of the longer side for BMS etc.

The first image with holes in the lid shows my wiring as an example - you'll need create holes in your slicer.

I got a socket one one side, for which created the cover, that comes as 2 "cap" parts.

Both cover and handle require inserts. 4 for cover and 2 for handle.

If you don't want inserts, close the holes in slicer and drill after printing.
