This is a simple mold to allow people to make their own sidewalk chalk crayons. It is inspired by the Bloxen, Sidewalk Chalk Mold 'thing'.

My boys used to use this stuff on our driveway all the time and they loved it!

Instructions

Print, fit together, hold together with a rubber band, pour in plaster-of-paris colored with powdered tempera paint. Let harden for ~24 hrs. Demold. Go outside and color!

Note the SCAD file is rather ugly... :p

NOTE: For demonstration purposes I melted five red crayons and poured it into the mold. It works for wax too. :p
