Summary

Bulky, Evil looking crown that holds 30mm, 7.62, and 5.56 shells to complete its design. Fitted to 7 1/2 inch head size, but can be padded to sit higher or fit smaller heads.

You may choose to print projectiles for any of the rounds, I highly recommend doing this for at least the 30mm cannon rounds to make the overall design more pointy. I used the following for the test model: https://www.thingiverse.com/thing:3730354

Post-Printing

Materials Required

Either 1x Full crown print, or 1EA Crown Front, Back, Left, and Right quarters
Optional, 4x printed 30x173 cannon round projectiles (https://www.thingiverse.com/thing:3730354).
4 30x173 cannon shells
10 7.62x51 or similar
18 5.56x45 or .223 remington
Padding material for fitting, I recommend using some kind of decently stiff packing foam
A decently strong 2-part epoxy or JB Weld for assembly

Assembly

Print either

Sand the base of all the brass shells, the base of each of the podium
If printing quarter parts, sand each of the joining pegs and the flat surfaces
Optional, paint the assembly
Snap-fit the 4 cannon shells into the largest podiums. Epoxy isn't necessary as these are exceedingly tight snap-fits
Put a small dab of epoxy on each of the 7.62 shells and glue into the medium podiums
Repeat for all the 5.56

For fitting, I recommend gluing 4" strips of foam, roughly 1/2" thick along the inside of the ring, then trimming thinner as required.
