120 / 140 mm Build Chamber Fan mount for CTC / Flashforge / Make

pinshape

I designed a quick fix to add two 120 or 140 mm fans, one on each side of my CTC's build chamber. My goal was to create a fan mount that can be easily removed when accessing the print bed from the side, like applying blue tape or capton tape. The bottom bracket has slots for adjusting it to different fittings since the CTC doesn't have high-quality control. I power all my additional fans using a PC fan-controller I built into my printer and an external 4-pin Molex PSU. I created two versions: one "full" with complete brackets, and a "small" version with split brackets for easier printing in ABS to minimize warping. Printer Settings: Printer: CTC 3D Rafts: Doesn't Matter Supports: Yes Resolution: 0.2 mm Infill: 25%, 4 Shells Note: The support is crucial for the "grooves" that hold the brackets on the printer's frame.
