This is a speed drive mount I designed for the ender 3 which mounts behind the x gantry bracket. This was designed specifically for the Bondtech LGX with its accompanying motor. As a result, the clearance between the back of the motor when mounted and the Z extrusions is very tight. As a result, I doubt this will fit many other extruder+motor combinations but you are welcome to try. However, this means that the hotend can stay in its default location so no buildplate area is lost.
Print Recommendations
IMPORTANT: I strongly recommend you print this in PETG or some other high-temperature resistant filament instead of PLA. From my experience, the LGX motor can run quite warm and so it might soften pla over time.
This model requires supports (see photos).
- Nozzle Size: 0.4mm
- Layer Height: 0.2-0.28mm
- Perimeters: 3-4
- Infill: I use Gyroid
- Infill Percentage: 10-20%
Installation
To install this mount, disassemble the top two v-rollers on the x gantry and slide the 8.35mm sleeve bushings from those v-wheels into their respectively-sized holes in the mount and reassemble the v-rollers. That's it!
Hardware
- 4x M3x6mm screws to fasten the LGX extruder to the mount.
