This is a jack-o-lantern flashlight diffuser designed to be printed in opaque plastic. Variations in thickness show a pumpkin face when lit from inside.
The OpenSCAD model can be easily edited to fit any size flashlight head.
I have included an stl model rendered to fit the $1 Ozark Trail 3-AAA 9-LED plastic flashlights I've seen at walmart recently.
The author marked this model as their own original creation. Imported from Thingiverse.
