Caja para tizas / chalk box

thingiverse

This year I can not share chalks with other teachers, so I have to carry my own supply of chalks with me instead of leaving them in the blackboard. I designed this box to keep chalks sorted. Or I would keep them that way if I was not color-blind. Please notice this box is designed from a batch of color chalks and it is a bit smaller than a standard white chalk So please break your white chalk in two pieces before putting it in the box. The cap is printed a little bigger so you have to shave it until it fits tight in the box I recommend you use an elastic rubber to ensure it does not open. *** I forgot most of my English. Please feel free to suggest grammar improvements ***
