ATTINY85 to control 3 RGB leds using PWM

After lots of small phases from prototyping on an ATTINY85 USB dev board (Digistump clone), to programming bare ATTINY85 using RPi Zero bitbanging, soldering the circuit onto a perfboard, to finally building a proper enclosure for my RGB lamp in FreeCAD and 3D printing it, it has been a fun ride! I learnt a lot through this simple project, even more than I initially expected.

Here are some more images documenting the progress:
