#272 – 28″h X 18″w X 18″d – THREE tracks – Chain lift – 3D printed flat funnels

This amazing, motorized desktop just has it all. A chain lift keeps it continuous for automatic rolling ball sculpture action. Three tracks are on display here. Track one is the loop d’ loop. Track two has a tall skinny coil. Track three has everything else… The tipping arm is adjustable so you can set it to tip with every marble or collect up to three before releasing them to roll on the tracks together. Lots of great track with sharp corner, dips in the track and a couple of my 3D printed gravity wells. Lots to look at on this RBS.

100% stainless steel, TIG welded.
