Gravity well fruit fly trap

Proven effective against annoying little flies in the kitchen.Updated to version 2- a much more forgiving print although I would still recommend printing at 0.16mm layer height.To start catching flies just add some vinegar and water to a glass and pop in an apple core to make it especially attractive. It may take a few days for the smell to start working.I don't know if the colour makes any difference but the white one that I am using at the moment currently has over 30 dead flies in it, so seems really effective. Happy hunting!
