Reading Bed Lamp - color controlled and timeout

A Reading Bed Lamp, with control of the color "temperature" and a gentle fade-out after a timeout. Color is set by rotating the base, doing so resets the timer.
The two parts that makes the ball clamp has a cone ending in contact with the base. It makes the ball of the 'nozzle' tighten.

Use the volume "support for base.stl" to generate supports only where it is needed.

C code for the PIC is here:
https://github.com/pierre-muth/Bed_Lamp.

It uses a PIC12F1840, a potentimeter, and a SK6812 RGB+W LED.
It can be easily done with and arduino as well.
