Sealed Coin Jar
by Rutter, published
A simple coin jar with an opening large enough for any Canadian coin (probably any size coin, but Iâ€™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. Iâ€™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.
