I made these out of semi clear luminous filament.
The original size was a bit small for the filament I was using because it's a bit brittle. My 2nd one was 60% fill and 200% scale. Sliced with 3D Simplify made with a FF creator pro with a glass bed. I used 4mm auto supports. Probably was a over kill but wanted the tail to come out good. I'm still quit knew to this printing only have 6 months under the belt.
