About this 3D model
This is a derivative of the Safe Box by BLINCOLN. I added a coinslot that is sized to take coins the size of quarters or smaller. I also added engraved text on the top surface. Use it for your bitcoins and other loose change. Caution, I am in the process of printing to verify fit as when I imported it for editing, the dimensions were scaled to inches and I had to scale it back to mm.
