Crayon Maker and Sharpener by CodeCreations

Pouring custom crayons into printed molds!

Pouring custom crayons into printed molds!

I’ve wanted to make a MakerBotted crayon mold for about as long as I’ve owned a 3D printer.  Now this is a reality thanks to Thingiverse citizen CodeCreations.  CodeCreations1 has shared his STL’s, OpenSCAD source code, and detailed directions for making crayon molds.

CodeCreations’ method involves using a printed container into which plaster of Paris is poured.  When the plastic is removed, it leaves a plaster mold with triangular crayon “troughs.”  Then it’s a matter of melting crayons, pouring the wax into the mold, and waiting for them to cool.

    Sorry to be a party pooper.
    Melting crayons with a open propane torch in front of kids
    could be a recipe for heartbreak.

    A double boiler is the prefered method of melting
    wax (or crayons) as it limits the temperature to well below
    the flashpoint of wax.
    I thnk the Idea of recycling the crayons is a good idea itself.

    Wow — I completely missed this when it was posted.

    Perry, responsible supervision is critical, of course, and every kid is different. If the kids don’t understand and respect the tool they’re using, then teach them, and protect them from making serious mistakes. I agree that a double boiler would be better for melting the wax.
