Gengar Pokemon Purge Plate I mocked up for Catherine Doucet's Poop Shadow Box.

Shouldn't be any need for supports with the tiny arches that link each piece together. Bonus of the arches is you can fit some filament poop in front of them to hide them a bit more easily.

Printed first time in black but personally I found it a little lacklustre. Try some brighter colours!

Enjoy!
