A super cool marble run that prints in just 3 parts!
Simply assemble the 3 parts and watch it endlessly move the marbles up and down. No support is required but you can put some on the track to make the clean up process easier.
To automate this you will have to buy a few cheap parts:
The Marbles(7mm Diameter)
The Motor(6v 30-60 RPM) T
The Battery (two 1.5 volt or a 9 volt depending on your motors voltage)/ USB cable ( Just dissect some old phone charges)
Overall this all costs £10
