In my idea of tidying up my workshop, I want to store my sandpaper.

So I create this box to store my triangle sandpaper (see [https://makerworld.com/en/models/1078740](https://makerworld.com/en/models/1078740) for round sandpaper box).

The most common sizes are provided and a version with no size written on it is provided so that the value can be put directly into the slicing application.

Details of the bin:

I followed Zack Freedman's Gridfinity specification for the bin size. I started from the specification described here: [https://www.printables.com/model/417152-gridfinity-specification](https://www.printables.com/model/417152-gridfinity-specification).

Some modifications have been made:

• I have changed the bottom of the bin: there is now only one magnet instead of four, which reduces the number of magnets needed. Additionally, the magnet is a bit larger (10x2) and central (no support needed)
• Compatible with any Gridfinity baseplate
