I bought a box of sandpaper rolls from Aliexpress, but paperbox had been destroyed during shipping.
Modelled this one to keep them organized, I kept the center roll, and the endcaps from the original packaging.
I guess at some point I also need to add a lid though.
The included .3mf file is for Prusa mk3, I used 0.4 nozzle.
