How can I cheaply and easily create stackable tiles?
Best bet for multiple "3d" sets: 3-D Print off a master of each type, then use resin casting to make as many as you need. Or use a single type, and print circular labels that go inside a recess.



As for bubble removal - an insulin syringe. that microfine needle barely leaves a mark, and can suck half a cc of air out.

It's better, however, to not get bubbles in the first place... so, you set an edge past the edge of the meaningful area, the use a rolling pin or squeegee to press it flat from there over. I've also found it better to expose the lamination and put the paper onto it, than to place the laminate onto the paper.
