Sneaky Bolt

thingiverse

This is a sneaky little bolt with hidden room inside, perfect for stashing cash or paper bills. It's easy to scale up to store coins too. Comes with a key that lets you open and close the secret compartment with ease. If you need a working nut to go with this bolt, I can design one for you. Just message me and we'll get started. Otherwise, enjoy your new sneaky hiding spot! To print out this clever bolt, you'll need three separate STL files: Key.stl, Thread_screw_with_Hidden.stl, and Hidden_Cap.stl. I used Cura 4.4.0 to slice the design. Be sure to use supports for the key and hidden cap where they touch the build plate. You might also want to adjust the support overhang to 80 degrees to avoid any unnecessary print settings on the threaded bolt. Check out the actual pictures added above for a closer look.
