Lil' Ghost Family

Is your life a little too haunt-free?

Supports are recommended, but you could try it without. I printed mine in glow-in-the-dark blue, but any color would look fine. If you use a glowing/transparent filament, make sure to pick an aesthetically pleasing infill pattern as it will be partially visible.
The larger two (Hii and Luv) measure 6 cm tall, and the little guy (Boo) is around 3.5 cm. Scaling them to be bigger or smaller shouldn't be a problem.
