A small and simple 9g servo mount for mounting directly onto the extruder carriage for use with the auto bed levelling function. Mine is mounted onto a Greg's Wade extruder body but would probably be compatible with more setups as it requires only an M4 mounting hole

I printed this in ABS given its proximity to the hot end and also printed it with the servo end on the bed which gave a better print quality on the small screw holes for the servo mount.
For the servo arm I used the already excellent thing from zennmaster http://www.thingiverse.com/thing:222861
