Monoprice Maker Pro radial fan duct

UPDATE: I called it quits on this design. I will keep it up in case anyone wants somewhere to start. It is here: https://www.thingiverse.com/thing:3537805 I wanted a lightweight and simple fan mount for a 40mm radial fan. This is intended to be a press fit over the inductive sensor, but you may need a nut to snug it down. The fan is held in place with a zip tie/ rubber band. Flip it 180 degrees and print without support.
