A simple coin jar with an opening large enough for any Canadian coin (probably any size coin, but I’m not sure). There is no way to get the coins out aside from breaking it, a nice throw back to the old ceramic piggybanks.Print at any resolution with a moderate infill, no raft or supports needed. The jar shown in the picture has 1mm walls, but I had a little trouble with it failing at the top and it took 2 attempts. I’m not sure if that had to do with the wall thickness or not, but just in case I also included a version with 1.5mm walls. The step file has 1mm walls for anyone who wants to make a few tweaks.
