Customizable Chore Magnet

My kids take turns emptying the dishwasher, and this is tracked on a calendar. They constantly claimed that they did not know it was their turn as they pulled dishes out of the dishwasher to eat from and never emptied it. They now have a clear indication that is their turn on the dishwasher itself, and I got to learn OpenSCAD. Win/win, at least for me.

This was designed around some 15mm x 3mm magnets I sourced online. It should be easy to pop in another size if needed.
