You can use it with any bulb you have, e27,e14, etc.

Please print it with supports, preferably standard tree supports.

It has about 1 mm perimeter width, but you can print it with 0.6, and 0.5 with the usual 0.4 nozzle, and even 0.3 works fine with 0.2 mm nozzle.

Easy to print with HS PLA, PLA, PLA+, PLA HD, etc. PETG is also a good choice. Please take into consideration that there will be random warping effects if you print it with ABS, which is not necessarily bad, but you have to take care of the speed and temperature.

The print time with HS PLA, 1mm is about 3.5-4.5 hr and consumes about 50m of it.

This is the first model I've ever modeled in my life, I made it in a modeling software for children, tinkercad, but tested it later on a variety of materials and 2 printers.

Looking forward to your feedback!
