For this project I designed and prototyped a pizza cutter that could be entirely 3D printed. This featured a print in place locking mechanism for easily replaceable and washable blades.

The handle with the print in place mechanism is printed in one piece with the blade being split in 2 down the centre to achieve a sharper blade. The whole design only consumes roughly 35g of filament with the replaceable blades being only around 12g.
