Description

Originally printed with PETG but can be printed in PLA or any other material really.

To connect the batteries I used M2 screw and nut, M2x6/8mm recommended.

Batteries can be connected in series or parallel (as shown in pictures, sorry for the mess).

The author marked this model as their own original creation.
