Technical summary
Crane highly optimized for light weight and printing speed (47 grams in total, only 1 gram of support)
Model made of 14 interlocking parts, requires a single M3 10mm screw for the rotating base
Educational project developed for a STEM course on 3D modeling with Fusion 360 and Arduino programming with mBlock
A base without an Arduino holder is also provided, so it is compatible with CyberBrick or other programming systems
All the electronic components are standard and easy to find: Arduino Uno/CyberBrick, 1-dollar SG90 360-degree micro servo motors, LED
The best way to control it is with a joystick module; I have attached photos that show it
