I've designed this adorable floating ghost to work with BambuLab's Magnetic Levitation Kit. However, if you don't have the kit, you can still use it with a tealight or puck light without the base.
I Made it in 3 parts that can be printed separately. The bottom base could snap in place to ghost body (it may not be snug enough depending on your print or filament, So I recommend gluing them to the main body as well as the heart to avoid getting them knocked off)
Printing Instructions:
for the levitation kit you need to print the base shell first then follow the instructions there for installation. You can download makerworld's version, Or other remixes. The one I have is a custom base made by pixelwave on makerworld
