Nut for E12 Candelabra Holder

2025 Update: I uploaded a new version that is exactly the same but with the libraries integrated into it so that the online customizer will work. The name is "e12_nut - use in online customizer.scad" I wanted to make some of the lithophane lamps here:https://www.printables.com/model/225160-lithophane-lampusing the lamp holders I purchase from here:https://www.amazon.com/dp/B07Z2PNNTGbut they only come with half the number of nuts needed if using 2 per lamp as I did with these lamps. So I designed a replacement nut.
