New from the land of Ooo! Getting a jump start on halloween costumes (looking likely to be Adventure Time themed), this is an adjustable Princess Bubblegum crown. It fits a head circumference of about 21 inches to about 23 inches.
Also coming soon or upon request: Ice King Crown, Finn's Demon Sword
Print 1 of each piece, and 2 of the pins. I recommend a gold or yellow for the crown pieces, and a blue (better if it's glow in the dark!) for the gem.
The crown was starting to droop always when it got to the gem part, so I split it off to print separately.
The gem will need to be superglued into the holder (it might just fit with friction) - and the gem holder will need to be superglued to the top of the crown.
The pins then snap into the front of the crown pointing inwards, so they can line up with the holes for the back of the crown. Fit it for your head, and then go do science or something!
