Graber I3 extruder support with servo mount
This is the extruder I designed with servo mount for Z probe.
The mount is meant for a 9g micro servo (like HXT900) and keeps a low clearance from hotend. That way the probe offset will be reduced increasing the area the probe can scan
Just print the part with no support and about 20% infill.
The extruder mount holes are 50mm spaced and the X-Carriage mount holes are 30mm spaced.
Enjoy.
