This model is inspired by https://www.thingiverse.com/thing:456900. It is made to be 7.4 mm narrower than the original, saving precious space in your models.
That is achieved by thinning the walls between the batteries down to 1 mm (rather than the original 3.5 mm). Therefore, the springs had to be completely remodeled.
It also has only 4 M2 mm screw holes and additional cable management holes at the anodes side.
Recommended Extrusion Width: 0.56 mm
Extrusion Width: 0.56 mm
Material: PET or ABS
Use thin wires (up to 1.3 mm in diameter) to connect the cathodes and anodes of the adjacent batteries, using the integrated cable management ridges and holes. Make a few loops around each contact, rather than welding, because you have to be really skillful not to melt the plastic in the process.
