Tumbler Guide for Ortur Rotary Attachment

thingiverse

While engraving tumblers with the standard rotary attachment, I was having problems with shifting and wobble during the engrave. Some other rotary attachments use adjustable guides to help stabilize irregular objects like metal tumblers. This can be printed all at once and takes around 3-4 hours depending on printer speed. You will need to print 3 pulley mounts, 3 flat risers, and 2 angled risers. Post processing may require some cleaning of the pulley mount hex hole. Assembly is pretty straight forward. One straight riser and pulley mount is used on one end and the remainder of the parts for the other end. Additional hardware required: 3 pulleys (I used the same POMs found on the engraver, but acrylic would probably work fine), 16 M4x8 (12's work as well if needed), 3 M4x20, 19 M4 nuts.
