Introduction: Masterdude K'nex Safe/Vault
I made this K'nex Safe/Vault some time ago. I most probably will not post an I'ble (~90-99% sure) so if you want to make it then you'll have to work with this. It uses 2 keys and they move back bolts which lock the door in place.
We have a be nice policy.
Please be positive and constructive.
