Classic Mini key holder with lights and a wobbling head, telling everyone that you are out!
If you are interested, this video will tell you all about it:

I've printed everything in PLA, except the lights, they are printed in transparent PETG.
Print MainChassis vertical with tree supports. Print hood vertical with normal supports. Also roof should be printed vertical, as this gives the most smooth surface. Print the light blocking cylinders in vase mode.
Check out the wiring diagram in photos.
You need following parts:
AA battery terminals
10x M2,5 x 6mm (roof, hood, chassis, batt cover and hook)
3x M2,5 x 10mm (wheels and adjust screw)
5x 3mm LED's
3x 1,5 kOhm resistors
2x 300 Ohm resistors
M4 nut (head)
M8 nut (weight)
Paperclip (0,8mm)
1x M3 x 15mm screw (head arm)
Reed switch
9mm ferrite disc magnet
I hope you like it!
