Crayon Sidewalk Chalk Mold

thingiverse

Create your own sidewalk chalk crayons by using this simple mold, inspired by Bloxen's Sidewalk Chalk Mold. Your children will love playing with these on the driveway. Assemble the mold pieces and secure them with a rubber band. Fill it with plaster-of-paris mixed with powdered tempera paint. Let it harden for about 24 hours before demolding. Time to color outside the lines!
