This is a cover to cover up the hole in the ceiling and the wires of a lamp. I used it for FP's Lamp shade boy https://www.printables.com/model/278422-lamp-shade-boy/comments/633437. Technically this is not a remix, but more of an add-on. Could be used for other lamps too.
I first inserted 3mm inserts in the mounting bracket (using a soldering iron). Then I mounted the bracket on the ceiling first using regular 3mm x 25mm screws.
The ceiling cover is fixed to the bracket using M3 x 10mm screws.
The author remixed this model.
