Wanhao i3 PSU Cover 120mm Fan Adapter

thingiverse

An adapter lets you mount a 120mm fan to the back of the control box/PSU of Wanhao Duplicator i3 (Monoprice Maker Select V2). This makes the control box quieter and keeps it cool during printing. Version 1.1 (Nov-8-2016, Recommended version) Thickened tabs hold screws that bolt to the printer. Enlarged bolt holes for AC inlet. However, using mounting tape instead of bolts here is still recommended. There are six variations: SameSide - The hole for the tether is on the same side as the AC inlet OppositeSide - The hole for the tether is on the opposite side of the AC inlet BothSides - The hole for the tether is on both sides, but there's only one hole for the AC inlet Invert - The bottom of the adapter is curved instead of the top. The top is flat. For underslung control boxes If you want your AC inlet to be on the right instead of the left side, mirror the STLs in your slicer. Version 1.0 (Old Version) Initial version, kept here for reference The bolt tabs are a bit weak. V1.1 is recommended. The adapter mounts to the printer using screws from the original metal back-plate. A fan mounts by sliding in from the top, using its screws as "hooks". You can adjust the tightness of the friction fit by adjusting these screws. I used this attachment method because the included fan screws were not long enough to screw through the fan into the adapter. On this adapter, both the tether to the rest of the printer and power cable exit from the left of the control box. There are screw holes to mount the power inlet. However, because the original machine screws did not bite into the printed plastic very well, I used exterior-grade mounting tape between the adapter and the power inlet mounting flanges instead. This turned out to be much more rigid than using two screws. I installed the adapter using hex wrenches that came with the printer. However, it was tedious because the wrenches are quite short. It became much easier when I used longer hex drivers. The fan I used is from a Cooler Master Sleeve Bearing 120mm "Value 4-Pack", but any 120mm should have the same screw pattern.
