BMG aero/wind mount with dual 5015 fans (for Geeetech A10/A20/A30)

thingiverse

BMG Aero + dual 5015 fans! For those who haven't come across this cool extruder design, Mellow NF's BMG Aero & BMG Wind extruders are basically a standard BMG extruder with a titan aero style heatsink built in (according to Mellow NF, the only difference between the two models is the heatsink fin shape). The heatbreak screws directly into the extruder with no need for the standard V6 style heatsink, allowing for even shorter retractions than a typical BMG direct drive setup. Very similar in concept to E3D's Hemera extruder, but with the benefit of much lower cost and compatibility with common E3D V6 heat blocks.

Of course, your mileage may vary. Edit: 9/13/2020 - Added 12mm NPN sensor bracket which mounts in place of the fan guard. Expanded fan duct mounting holes to slots to accommodate a small amount of height adjustment. Use washers on your screw heads.
