I wanted to make a unique toy for the Christmas tree. I managed to make a balloon design made from the OPEN BUILDS profile. The organic lines of the branches of the Christmas tree smoothly merge into the details of the printer located inside the branches. The printer's head and bed are moving, and the filament spool is spinning, making it look like the printer is working. It was difficult to realize this without losing the lightness of the design. The mechanism is very simple. Hidden inside are the motor and crankshaft, which are powered by a 2032 battery. The backlight is made of flexible neon. I'll give the toy to my friends.
