Third try is the charm!
I'm working out in my shop, despite the cold, to finish a project by Friday. This does mean you'll see my imperfect foods box post tomorrow, though it came in tonight.
Looks like a handle, right? It's a tracing pattern for a dice carrier. Using the screws as both a way to secure it in place, and a guide (roughly) for the magnets to be placed. Each box will get a top and bottom with this cutout, hopefully they match up nice and boom, I get to be a woodworker.
