I have revisited my (mostly) 3D printed Xmas Pyramid. I have replaced the previous fixed speed, fixed voltage, geared (noisy) motor with a stepper motor, driven by a TMC2208 driver module which has made it silent (at least to my ears). I've also replaced the LEDs with new, WS2812 addressable LEDs and use a Wemos D1 mini running ESP home to simulate a flickering candle effect. Finally, I have made a new drive shaft to replace the previous threaded rod. This is in sections for easier storage and along with redesigned rotating discs, allows tool free assemble.
