I tried using a few of the other Chalk holders listed on thingiverse and I gave up on them.

This Chalk holder is designed for use with 9 mm chalk. (I believe this is a standard chalk size in America.) It has teeth near the end that lightly grip the chalk so it doesn't slide around. Then when it is held in your hand the pressure from your fingers tightens the grip so the chalk will not slide. It is easy to slide the chalk in and out when you want. In fact if you push the chalk in past the teeth it will freely slide up and down inside the holder. 

If you want me to make another version of this for a different size chalk please ask me in the comments. Tell me the size you want and I will make the change.

PETG Reccomended. It needs to be a little flexible.

Printing one at a time gives better results.
