Sub-C Battery Jacket

thingiverse

Human: I created a jacket shell specifically designed to house sub-C batteries, which are commonly found in RC battery packs and power tools when broken down and exposed. One of the key issues with these batteries is that they can easily short out if not properly secured due to their flat metal surfaces. This is where my design comes into play - by keeping the anode and cathode accessible while shielding the top end from coming into contact with a conductive surface, it reduces the risk of shorts occurring. The jacket shell features a clip-like inner ridge that securely attaches to the sub-C battery cell, preventing it from sliding out. To assemble the device, simply place the jacket on a flat surface and gently push down on the battery until it snaps into position. I have also provided cap versions and a 32mm variant specifically designed for 3/4 sub-C cells. At present, all of these designs have been printed using PLA, but I have yet to test their performance with batteries actually connected inside them. For those looking to replicate my work at home, the STL files are provided below: * subc_jacket.stl is compatible with a 42mm (1.7") sub-C battery. * subc_jacket_cap.stl includes only the cap portion for sub-C cells without the full body. * subc_jacket_32mm.stl is designed specifically for use with a 32mm (1.3") 3/4 sub-C cell. For optimal printing, I recommend the following settings: * Printing software: Cura * Layer thickness: 0.2mm * Shell thickness: 0.3mm * Filling density: 100% Due to the extremely thin nature of these designs' walls, I advise caution if you choose to modify or adjust the printing settings to avoid any gaps or weak points in your printed shell.
