I designed an alternative battery box for the Tarmo 4 RC car cause I am using a bigger battery (3S 5200 mAh, link below).
The battery housing is made of two parts assemblies with M3 bolts (CHC M3x40). The using of nuts is better for avoiding looseness.
The upper part has vertical and diagonal louvers which are better for 3D printing than the horizontal origainal ones. There is a small axial stop with a small hole for passing a cable clamp through.
The lower part has the same interfaces than the Tarmo 4 battery box. It is simply bigger for containing the bigger battery. I added a bigger clearance with the drive shaft cause I am using a really big PLA driveshaft with my car (link below). Finally, there is a groove for passing a cable clamp through.
Printing parameters:
0.2 mm layer height
4 perimeters
20% gyroid infill
No supports
Happy printing!
