Wanhao D6 Motherboard 140mm Fan

thingiverse

I liked mentalbob's 60mm fan mount to eliminate the noisy 40mm fan (they're ridiculously loud while moving air and I had a bearing go out at the three-month mark making it even worse). The only issue I saw with the original was that I would have preferred more fan coverage on the board. I remixed a version with dual 60mm fans and it's much quieter but could be nearly silent. I remixed this 140mm fan mount. I beefed up the legs and extended them to 25mm so you don't have to print the standoffs from the original design. Depending on the fan, it may need to be mounted on the outside of the bracket and the cover left off the bottom of the printer. Edit: Apologies for the mistake, the fan I measured was a 140mm (~125mm mounting screw spacing, on center), not 120mm. The current model has a larger base, reflecting correctly sized 140mm fan, so it doesn't restrict as much airflow.
