This is a unicorn horn that can be used for costumes. The ring of holes at the base of the horn allows for sewing onto a wig or other cap. It has a rounded point to prevent accidental stabbings when being worn.
This is 215mm tall (~8.5in) as modeled can be printed without supports. I printed in PETG at 0.2mm layers with a small raft.
I used this for a halloween costume for my daughter. We used stretchy elastic cord (sold for bracelet beading) to attach it to a rainbow wig and added an LED strip down the middle to light it up in the night.
