Instructions
1. Route or laser-cut out the individual pieces captured in the SVG files.

** Inner Layer x 2

2. Depending on manufacturing process artifacts, may need to grind and polish surfaces for a better seal. May need to bevel the edges in the heater-wire wrap area to prevent failure.
3. Assemble on bolts in order from outside to inside, back to outside. Check orientation at each stage to make sure pass-through overlapping points orient correctly to see through to next layer.
