Life Size Medieval Key with secret compartment

This is a life-size 3D printable medieval-style key with a hollow interior, perfect for storing items or using as a decorative prop or for cosplay. The key opens with a functional screw mechanism in the middle so it is easy to use.

I designed this in Fusion 360 and printed it all on my A1 mini. It is easy to assemble and works well on other printers aswell. All STEP and Fusion 360 files are included, so you can customize the design, add engravings, or modify the handle to make it uniquely yours.

Assembly

Regarding assembly, all parts are meant to be glued together. The tolerances are around 0.1 mm to 0.2 mm and the pieces will stick together just by pressure therefore make sure that you apply the glue before putting it together. The part of the assembly you need to be most careful is whenever you are aligning the screw with the rest of the model. I haven't added any guides to the parts and therefore you can easily glue it in a way where key doesn't align when you glue everything down. make sure the key pin and the other part of the screw are screwed in. 

I also used the rings to hide the parts where I connected it together. This way you won't see any seams. 

So far I am done with this project. I designed this for someone who wanted creative way of asking his girlfriend to move in together with him :) He came up with the idea of hiding his keys inside this bigger key so all props to Elwin. This is also based on different models but the one he sent me for reference was the Old Castle Key by RSdesign3D. 

Because this is done I won't be making any changes unless someones specifically asks to. I think there is lots of potential since it is right now quite barebones and you can easily add more details to this. Feel free to remix it and ask for help in the comments. I also love to see images of someone that has also made this!
