Sidewalk chalk holder

thingiverse

After gazing at the bucket of shattered sidewalk chalk that my grandson had, I realized it would be an excellent idea to design a holder for the chalk. This is tailored specifically for the chalk with a diameter of approximately 1 inch at its largest end and a length of about 4 inches. Print both the holder and the ring, then slide the ring onto the holder before inserting the chalk inside. You can withdraw as much chalk as desired and then push the ring upwards to tighten it securely like a collet. I deliberately designed this so that there's no need for additional supports.
