What can I use in place of acrylic for my mock-up/prototypes?
I'm working on a custom-made pencil case and I intend to do the final version with a lasercut acrylic-sheet that's been shaped around a positive wooden shape. I'm still working on the details of how I want to place the cuts and lines, and would love to be able to make some quick prototypes that I can draw on and carve out (maybe something paper-based?), but I'm short on ideas of how to do this and what materials and techniques to use.
I've added an image of the positive shape and some sketches (sorry for the crappy quality).The shape can be split in the middle to allow it to be pulled out at the ends after the acrylic sheet has been shaped around it,
