This is a project that my daughter and I came up with recently that I thought I would share. Once you have the mold made then you can melt old broken crayon pieces in the oven to make Heart shaped crayons.
Needed
1/4" 3-flute flat end mill
1/4" 2-flute ball end mill
Aluminum billet: 2.75" x 2.75" x 0.8"

WCO
To make this part you just need to zero the WCO (G54.1 P11) on the center face of your stock.
Make Crayons
- Place a sheet of aluminum foil on the bottom of the oven to catch spills
- Preheat oven to 100-200 degrees F
- Break up crayon pieces into smaller bits (around 1/4" or smaller). You will need about 3 full crayons worth of crayon
- Place crayon bits in the mold and the mold in the oven
- Keep an eye on the project in the oven for the crayons to fully melt. This will take around 20minutes.
- Once the crayons are fully melted turn off the oven and crack the door open
- Wait for the crayon to solidify and the mold to cool. This will take around 30 minutes
- Transfer the project to the freezer
- Once the crayon is completely cooled pull the project out of the freezer and the crayon should pop out of the mold
