Giá đỡ bút cơ bản cho LR3

Quick and dirty pen mount for the LR3. 

Use cable ties to mount it to your router, and the pen to the mount.

There are two mounts with different thickness arms. Depending on your nozzle size and slicer settings one will print better than the other. I suggest printing them both and using the one with the softest flex.

Awesome to use with Jamie's “squareness test marks” or a lot of his other gcode's from his generators, https://vector76.github.io/gcode_tpgen/. This allows for very easy Y axis calibration.
