This is a battery holder for 2 rows of 6 pairs of 18650 cells (from recycled laptop batteries). It is used to create a 24 cell parallel block for use in a 1kWh DIY powerwall.

Print two per block. I printed one in red and the other in black. So if you want a "24v" pack you'll need 14 of these in total.

This design has a 1 layer skirt to reduce warping on my little Printrbot Jr (which has an unheated bed).

This thing was made with Tinkercad. https://www.tinkercad.com/things/lft19zWDf7f
