These are the types of household projects that make having a 3D printer worthwhile! Saved about $65 by making my own door handle.

My buddy has a laser engraving business and wanted a jig for his rotary tool so that he could attach the tumblers to the jig and let them turn while engraving. I designed this one for a 40 ounce tumbler. It has been verified to fit Stanley and other generic tumblers. It is meant to fit the jigs with adjustable arms and holds in place with tension. If you need changes to the design for your particular situation, let me know and I will see what I can do to help you out. Enjoy!
