Iqietoy Hand-Crank Gear Lift 3D Wooden Marble Run turns into a crank-driven marble machine where a big gear carries each ball up and the track sends it rolling back down.
Why it is listed here
It keeps the marble run idea simple: one large lifting gear, a crank and a track, with no motor or batteries to manage. The footprint of about 10 by 9 in suits a bookshelf, and the basswood plywood pieces are machine cut and listed as burr free. It is a good pick when you want a mechanical marble run that you power yourself.
What the build involves
The listing says the build can take a few hours, so plan a relaxed session rather than a quick one. Run a marble through the track before the final level is fixed, so you can correct any section where it stalls. A little wax on the crank axle and gear teeth helps the lift turn smoothly.
Before you order
