JGAurora A3 BondTech QR Direct Extruder / E3D V6 Hotend Mount

thingiverse

This is a mount for the BondTech QR Direct extruder with E3D hotend on a JGAurora A3 3D printer. I designed this with ease of printing and maintenance in mind to make it straightforward to use. You will need short heat-set threaded inserts for m3, m4, and m5 screws which are widely available. Additionally, you will require the M4 and M5 socket head cap screws listed below. I aimed to print with materials other than the basic PLA and ABS, so I sought a different extruder setup to allow for more exotic materials. The issue of PETG filament jamming persisted because the teflon tube in the heat break would get damaged at higher temperatures required. An all-metal extruder solves this problem, so I opted for the Bondtech extruder with an E3D v6 available from MatterHackers. This mount makes the Bondtech/E3D setup essentially a drop-in replacement. It keeps the X and Z positions the same and relocates the Y position a few millimeters forward for clearance of the BondTech extruder stepper motor. The original turbo fan works without modification. As there seems to be interest in this mount, I thought it was time to update it. I have modified the turbo fan mount bracket to allow the original m3 fan mount screws not to bottom out in the bracket.
