Simple can crusher

I saw this on Joel the 3D printing nerd's channel but it was for tall, slim cans. Unable to find the original one to modify, I created my own to fit standard 330ml cans and decided to upload it here in case anyone else wanted to try it out. I printed both parts from PLA. The plunger should be ready to print with your slicer, but the holder needs to be flipped to avoid supports. There is a bit of tolerance between the can holder and plunger, but if your printer has Z wobble or over extrudes a bit you might find it a tight fit. If this happens, you can sand down the edges to make it fit or reprint the holder scaled up slightly. To operate, place the can in the holder, squeeze it through each of the 5 slots and push it down with the plunger. This creates a nice little compressed package which so far hasn't left any sharp edges for me. It's pretty much an exact size to hold the can, making getting the plunger in a bit of a challenge, but squeezing the sides of the can helps by lowering the top a bit.
