Orca 0.3 Z-Axis Opto Mount

Hi, this is my design for a Z-Axis opto sensor mount for the Orca 0.3. It is much more secure than the cable tie method, and follows on from my X-Axis Opto Mount. (http://www.thingiverse.com/thing:14155).

The parts position can be adjusted easily, just slacken off the nut and bolt, move it to where you want it, and tighten back up.

v2 - uses method similar to orca 0.40. One bolt adjusts, the other bolt and the 8mm bar guides. The spacers are used to tighten the bolts with nuts to stop them
