Bamboo Box
A box made of small (Cooking Concepts Bamboo Cutting Boards, 8.625x5.875 in. ~8.35mm thick) bamboo cutting boards from a dollar store.
Notes
Uses blind miter hidden box joint joinery and requires a 1/8" diameter 90 degree V endmill (#390) and a #282 --- instead of a #102, a 1/8" downcut endmill will minimize the need for post-processing.
Set the Z origin 8.35mm above the surface of the wasteboard.
It will be necessary to square up the opening on the front to admit the lid.
