Jack Daniels Bottle Lamp

thingiverse

Simple way to convert a bottle into a lamp with no glass drilling or cutting. A "plug" for bottles with ~18 mm inner diameter. I was considering making it screw on the bottle but was worried that the wire may not be at the back of the bottle. The thread is about 27 mm diameter with 2 mm pitch. This worked for the lamp holder I used and looks like a generic size (at least in my country).
