Ender 3 wiper brush holder

These are wiper brush mounts for the Ender 3. They attaches to the two bolts on the right side of the X-axis and requires no modification to the printer. The only difference between the two is the orientation. They both can be printed without supports. The brush needs to be glues onto the part.

The brush moves with the Z axis and can be used on any layer.

The brush should be at around 235 to 249 on the X-axis.

You will need to enable wiping in Marlin 2.0 if you want to use G12 to wipe. G12 in action:
