50mm 2in Abrasive pad holder

I printed this out of PLA with 20% infill just to give it a quality tool feeling. It has pockets in the base for magnets if you wanted to have this be mounted to a fab/weld table. Tops are optional but add a nice touch. I have the roloc style scotchbrite pads so I designed a grove for them to fall into. Each bay is labeled course, medium, fine. It should be able to accommodate any 50mm abrasive system you want to store.
