A spiky crown made for a costume project. Creating something like this with solid modeling isn't ideal...

Overall dimensions: Diameter: 140mm (5.5") Front spike height: 160mm (6.25") Other spikes height: 110mm (4.24")

If you want to print with support, I've provided the full model. Depending on the size you want the the printer you have you can either print the separate pieces or print as the top half and add the bottom spikes onto it. Keep in mind the size is smallish, so it may need to be resized for larger heads.

For large printers print: 1XCrown1-TopHalf 1XCrown1-FrontBottom 4XCrown1-Bottoms

For Smaller printers (Sized for Thing-O-Matics) Print: 1XCrown1-Front 1XCrown1-Left 1XCrown1-Right 2XCrown1-Back (Can be printed 2 at a time in an array) 1XCrown1-Topper 1XCrown1-FrontBottom 4XCrown1-Bottoms (Can be printed 4 at a time in an array)

All the pieces are tabbed so they'll fit together when printed. When we assembled it, we glued everything together using acetone.
