This Jig is for use with the Acmer S1 laser engraver and the Acmer M2 rotary setup for engraving tumblers, cups, etc. I created this Jig since there is no real first party method to raise the laser engraver to fit the rotary beneath it. I made the assembly modular for easy storage when you don't want to use your rotary. Using this Jig can allow you to create tumblers more efficiently without setting up and re aligning every project. Feel free to add on to this setup with other things you might seem useful.
