Today, I've added a frame and socket to support my 70s lampshade. Both can be printed on your kitchen 3D printer. I've used Creality CR6.
Almost the complete lamp can be home-printed now. Only light-bulb, wires, switch and power-plug need to be aquired. I salvaged them from obsolete electronics.
If you use my design and make your own lamp (it is really easy), please send me a photograph of the finished product. Just because I like to know and like to see. Thank you.
