This is a tensioner for the OMTech Polar stock rotary system, which helps keep tumblers pressed against the rotary wheels and prevents slipping and wandering. Tested with the "small diameter" rotary and an Rtic 20oz tumbler.
Parts needed: one skateboard bearing, and two 22mm o-rings. Note, you could probably skip the bearing sleeve and o-rings entirely and instead use some tape on the outside of the bearing just to prevent scratching the tumbler.
Assembly: Push the bearing onto the arm, then install it onto the existing tensioner screw (between the two rotary wheels). You may need to remove the rotary cover. Make sure to pull the whole tensioner and screw “downward” while tightening it back up, because that screw actually secures the belt tensioner inside the rotary cover.
This isn't very well tested for durability, but it does seem to work quite well at preventing slipping and wandering while rotary engraving.
I printed in both parts with Creality Hyper PLA, 20% fill, 4 walls, .2mm layer height. I printed the arm standing upright, with supports.
