MD Mellow BMG Aero Extruder Ender 3 Mount with CPAP Cooling

Mellow BMG Aero Extruder Ender 3 Mount with CPAP Cooling

This is the next evolution of my cpap designs for the Ender 3 (https://www.thingiverse.com/thing:3307633), this time going direct drive using the "Mellow BMG Aero Extruder" which is like a cross between a Hemera and a BMG. Also houses a 20mm thick 40mm noctua cooling fan, bltouch and an adxl345.

I went through many iterations to make sure the duct does not warp/bend/melt over time as I printed it in eSun PLA+ (should probably reprint in htpla/abs+/peek/something with better tolerance for heat.

Kit

• The extruder/hotend https://www.aliexpress.com/item/4000084805415.html
• Maybe a drill+tap for optional extra hole into the Ender 3 backplate. (stops possibility for backplate flex)
