This is a simple can crusher for 16oz/500ml soda cans. I printed in PLA. There are two sets of models to choose from, The non-combined version prints the Piston and Piston Cap separate along with the cylinder and cylinder bottom. OR you can just print the Piston Combined and Cylinder Combined prints. When crushing a can, it helps to squeeze the sides a little, like a pre-crush. Can be stepped on or pushed down with hand pressure. Note the photos of from my 12oz version of this project. The prints are the same, just larger to accomodate the 16oz/500ml can size. Will print and test soon but feedback is helpful.
