Z Opto-Flag Holder

thingiverse

To add a Z-Opto-Endstop on my RepRap at Boston's Museum of Science, I opted not to glue the Opto-Endflag and instead used a holder based on Prusa IT2 design. The first Z-homing with this part can be seen in this video: http://youtu.be/zNhn5zM340Q. The Opto-Endstop holder, as well as one with a mirrored arm, are available at these Thingiverse links: http://www.thingiverse.com/thing:21654 and http://www.thingiverse.com/thing:266696. To assemble, print the object, create a tin Opto-Endflag from a tin can using tin snips, wrap it with blue masking tape to avoid reflection, line up with the printed part, mark hole locations, drill holes with an M4 bit, fasten flag with two M4 bolts, and attach holder to X-axis with an M3 bolt.
