After installing some Ikea bathroom cabinets I wanted a place to keep spare TP and hold my bluetooth speaker, along with a cord path for the charger. I whipped this up in Inventor and am quite happy with the result.

Seeing that the foam cheese grater hats were hard to come by, I decided to make my own. Had to split it on a P1P but if you have a taller volume printer you might be able to do it in one piece so that file is included as well.
