Flexible 40x40mm DC fan coupler

thingiverse

This coupler attaches a 40mm DC fan to a flexible hose, designed specifically for exhausting carcinogen gas from enclosed 3D printers, especially when printing ABS parts. The small flow rate of the DC fan ensures that heated air is not sucked in, making it ideal for those printing large parts with ABS to prevent warping. This coupler is highly flexible, allowing it to rotate 360 degrees in one direction and 80 degrees in another, providing a secure attachment to the hose. Print Settings: Printer: Zortrax or any other printer Rafts: Not required Supports: Yes Resolution: 0.2mm Infill: 70-100% Notes: Rotate to 90 degrees before printing. Create supports using your 3D printer software. I designed this coupler with ease, utilizing the "revolve" feature. The design is a ball socket type with a hole at its center, based on a 40x40mm ADC motor and matching the mounting holes of the DC fan.
