About this 3D model

Wanted a quicker way to engrave 20 oz Polar Camel tumblers on our fiber laser engraver that held them centered (within reason). Created this from PLA. Springs are meant to provide the same amount of force to the sides to help keep it centered. Push against the bottom for repeatable locations. Printed on an X1 Carbon with .2 strength settings. This has not been tested with other brands of tumblers, only Polar Camel. Imagine it is close if it doesn't work. I ask that you not sell this print, I spent the time creating this design.
