Having turned our metal fuse box in the hallway into a chalkboard, i spent months searching for a cute chalk storage method, before remembering I had a goddamned 3d Printer! Designed to look like a classic chalk pack, I used these to race my 2 FDM machines, and both printers super well with no supports, even in that big wide colour window! The packet has space for 6 standard sticks of chalk, and space on the back for either large or small neodymium magnets to hold the case against a magnetic board. You may want to add some felt over the magnets to A) reduce scratching, and B) use as a chalk eraser.
