CNC Sunglasses- Setting Up

I've finally begun the complicated process of carving my sunglasses on the CNC mill!

I started by scaling the glasses in Maya, using ctrl t to view the dimensions in centimeters. It's roughly 17 cm across and half a centimeter thick.

I exported the file as a .stl for the CNC cutter to read

I needed a material for the first draft, and I didn't want to waste time carving a 2 x 4. Instead, I cut out 2 pieces of plywood a little larger than my sunglasses.

After tacking the pieces together with spray adhesive, I left them in a vice overnight. Each slab is about a quarter centimeter thick, so I glued them together to get a half centimeter of thickness.
