Car Body Shells
The basic car framework needs a food safe covering to go between the cake and the electronics. Thankfully when I bought my vacuum former this project was already on the cards so it's a perfect excuse to use it. I laser cut a basic mould from ply and assembled it as a mould to form over. The cake needed to clear the wheels and provide turning clearance for the steering. These covers came out pretty well, the trouble is that vacuum forming works best with a 3 degree angle on the edges and the laser cutter cuts perfectly vertical so it was a bit of a struggle to get the mould out. This was when I introduced an air pump to the vacuum former. Applying a bit of positive pressure after forming releases the mould a little and made it easier to remove.
