Wanhao D6 and Monoprice Maker Ultimate (MMU) Blower for BL Touch

thingiverse

I stumbled upon Empiricus's 5cm blower sometime ago and desperately wanted it badly. I had reached my limit with inductive and capacitive sensors and was eager to switch to the BL touch so I could go back to printing on glass for that incredible first layer, unfortunately this blower wasn't designed for the BL Touch. After much trial and error with Fusion 360, I finally managed to produce the attached design. The blower is very specific - it's the EBM-PAPST RLF35-8/14N. It's incredibly powerful and it's the only blower that this design is tailored for. Many people are hesitant about the price but it's well worth it. Please check Empiricus's page (again, see source files) for many of the instructions as I only modified the sensor component of his design. All of his other instructions remain valid. I used the mounting screws that came with the BL Touch. I believe this may block about 7mm of the build area at the back but am still conducting some testing. The probe offset is X = +40 Y = -22. Be sure to adjust your firmware settings accordingly. Also, the sensor height above the nozzle is 8mm which is precisely the required height for my version of the BL Touch (which is 8mm +/- 0.5mm). I welcome any feedback you have.
