A thin shelled cover that slips over conventional miniature incandescent Christmas lights. LED lights can be fitted if the hole is reamed to fit but they are too dim and too directional to work well with the cover. White or translucent filament must be used. The top can be glued to the base with acetone or other suitable solvent for the type of plastic used. Made with a Solidoodle 3. If it can be printed on this machine, it should work on anything. I used this as a test to get thinwall printing configured in Skeinforge.
