There isn't a category for plastic on this website, so I guess I'll post here for now.

I have a CNC router (Shapeoko 3) that works well. I would like to machine stuff from thin sheets of plastic (<3mm thick). I'm trying to machine stuff that is 1.5mm or 1.6mm thick.
I do know of the tape and super glue method and it does work quite well. What I noticed however, is the amount of time needed to set everything up. Putting the tape on the work surface, putting tape on one side of the plastic sheet, then placing superglue to adhere them together.
It does a great job at holding the piece while machining but because of the amount of time it takes to set it up, I'm curious of alternative methods of mounting the plastic sheet. I'm aware of the vacuum option but a lot of the pieces I make has a lot of holes (some stuff I made has more square-shaped holes than material, haha).

Are there alternative ways to mount the plastic sheet onto the work area that's faster than the glue and tape option?
