This lamp is a modified version of a design that I found at the link https://cults3d.com/en/3d-model/home/rgb-led-lamp. Since I didn't have the required switch, I made some changes to the main structure and reinforced the top of the lamp slightly. That's how this modification came to be. I'm sharing it for the record, or perhaps someone might find it interesting to replicate this project. The basis for this lamp is an LED strip that is controllable and can be used with a remote control.
