115mm Angle Grinder Cutoff Wheel Holder

I wanted a holder for some cutoff discs for my angle grinder. I couldn't find a container that would fit on my print bed (125mmx125mm) despite the fact that my angle grinder takes 115mm discs. So I had to design one.
To reduce the size, this container uses the center post as a screw-thread to hold the lid on.

This container has 20mm internal height, so can hold 3 or so grinding wheels or 10 or so cutoff wheels. More than enough for me who often only has a single grinding wheel and a couple cutoff discs.

Prints without support and the screw thread is pretty chunky so it should be pretty tolerant of print inaccuracies.
Made with blender and the source blend file is included. It shouldn't be too hard to mod for different sizes.
