18650 x40 case

A module based 18650 battery pack.
Print the connector to join multiple x40 packs together, as many as you want!
Print the attachment board to mount stuff on the side of the pack.

(Added 15-09-2019) My 40p3s pack of old mixed type 18650 cells is still working great. i had a few cells go dead on me (cant hold charge for more than a minute), but that is because some 18650 cells just charge quicker than others and so they would over charge. I'm choosing natural selection for that problem.

For one module (with up to 40 cells), you will need: 2x Lid and 2x BatteryHolder. If you don't plan on using springs inside the BatteryHolder, you probably want to design your own Ring parts to suit your needs, because the pack height will be different in height. Otherwise, print 2x Ring aswell.
If you plan on more than one module, print one or two HolderConnectorWide to connect two BatteryHolders together.

The Handle part will only fit like its shown on the pictures; across 3
