Summary

Hollowed version of the original model, resized to fit in electronics.

I recommend to print one side of the body as a whole (with a bit of maneuvering it will fit on the Prusa Mk2 bed), the other in parts, glue the neck and tail, do postprocessing, add electronics, test and then glue the middle of the body (and the head, legs etc...).

Post-Printing

Electronics

I'm not very good at electronics, so I'd rather not embarrass myself with my circuit design. The basis is a monostable flip-flop circuit with IC555 switched by PIR module for arduino and 3 RGB LEDs.

In the base there is a place for microUSB (https://www.aliexpress.com/item/4001143005133.html) for power supply, a small power switch and 3 holes for USB (https://www.aliexpress.com/item/1005005359666110.html) so that the Watcher can also serve as a charger.

The watcher itself is powered through the legs, has electronics in the body and a PIR module in the back (some module types need to grind the edge of the detector lens to fit). Three 5mm RGB LEDs fit into the holes in the "eye" (only the pins for blue and red are used).
