Easy to print, need little support.

When putting parts into lamp do not screw very hard - use light force so it doesn't need to be screwed through the whole thread.

As controller you can use ESP8266 + NodeMCU V3 modul (base is designed for it). You can flash it with software like WLED (which I recommend): https://github.com/Aircoookie/WLED/releases

Use Addresable LED RGB strip (preferable waterproof one - as silicon on light will separate it from direct contact with silicone down).

After attaching the LED RGB and connecting it with the controller, use glue spray to attach silicone down to it. Do it with many small layers - that way it will last longer.

Then connect it with a power source through a USB cable. You can plug it directly to the power supplier or to the power bank.

When install WLED mobile app, connect controller to your home router and use :) You can integrate it with smart home using for example Home Assistant.
