Print the shade in vase mode and make sure you get the same thickness on the bottom as the sides. Your bed needs to be properly levelled to get a good surface finish on this part. The strain relief is optional (but always nice to have) and uses two 10mm m3 screws. The rest prints as usual with no support. I recommend 3-4 walls to reinforce the frame.
Assemble the three frame parts. The little knobs are there to help align the pieces and may even hold the frame together, but I still recommend gluing it for stability. Cover the bottom in as much LED strip as you want. I use 7W and it can definitely handle a bit more. The shade simply rests on top of the frame bottom.
