I was making the vault, and when I went to buy the dowel pins, I decided to just design them myself, and thought others might want to as well. So here they are.
The Link to the Original vault by Rocco's stuff is here: https://www.printables.com/model/740370-vault-with-combination-lock
WARNING:
The 3D printable dowel pins do not rotate quite as perfectly as the metal ones would, but I used them to make my vault, and they have worked well. I also recommend using grease, or coconut oil to help them work more smoothly.
If you like the model, go here to see my others!
The author remixed this model.
I didn't alter or add any files to the original vault, just added 3D printable Dowel Pins.
