The file 'Opus BT-C3100 – 80x80mm 25mm Fan 3D Printer Model' is (stl) file type, size is 96.0KB.
Using ShrimpStar design as base, I added:
1 - add ventilation roles, helps to dissipate the heat and use less material to print;
2 - increased the diameter for the fan screws holes;
3 - added extra holes so you can use a zip to tie the fan instead of using screws
The fan to be used needs to be 80x80mm and 25mm thickness or less.
The original fan voltage is 12V. (measuared with a multimeter while charging batteries)
