Maker select v2 Fan shroud and z-probe mount

thingiverse

I designed this fan shroud to accommodate an inductive bed sensor for use with the Monoprice Maker Select v2.1 and Wanhao Duplicator i3. This remix is necessary because the original design isn't compatible with a z-sensor mount, so I made some adjustments. The top of the shroud was shaved down slightly to raise it about 4mm above the nozzle. It still uses the stock 40mm fan with the same screws as before, requiring no additional hardware. I used this specific sensor: https://www.amazon.com/gp/product/B07NYD4MVC Brown goes to +5v (use the ICSP header), blue goes to z-endstop ground (you can check which wire using a multimeter), and black goes to the z-endstop signal wire. My printer is running Marlin firmware. The sensor triggers at approximately 2mm with the stock aluminum build plate. However, it may not work well or at all with glass, but if you're using a steel or other ferromagnetic build plate, this setup will perform even better.
