Tronxy X5SA PRO Direct Drive BMG-M + Mosquito Hotend Mount

thingiverse

This is my custom direct drive conversion for the Tronxy X5SA-PRO, featuring a Bondtech BMG-M extruder, Mosquito hotend, BLTouch, and dual fans. Although it may also work with the X5SA, I have not tested this. I'm using the LDO Nema 17 motor for my extruder, which has a 26mm body: https://www.printedsolid.com/products/ldo-nema-17-motor-overthemoon-ldo-42sth25-1004ac. The STEP file for the mount is included in case your stepper motor has different dimensions. This mount attaches to the stock carriage using the stock bolts that hold the two sides of the carriage together. Remove the two standoffs that the original hotend was mounted on. I used fluid simulation while designing the shrouds to maximize airflow right at the nozzle tip. Note there are two fan shrouds (one labeled "right") because the nozzle is slightly offset from the center. You can get away with mounting just a single fan, but I've provided a set of spacers you can print to mount a second fan on the right. The BLTouch is offset 34.5mm in the Y axis and 2.7mm in the Z axis (although I'm using 2.5mm with my Duet and it seems to work perfectly). This version does not include a mount for the X-axis homing switch as I am currently using sensorless homing with my Duet2.
