Double Helix Tower LEGO GBC Module

Posted by on May 22, 2016 in LEGO | 0 comments

This LEGO Great Ball Contraption (GBC) module uses Nicolas’ (Nico71) ball pump to push the balls up through the tower. The balls then roll down a rotating double helix that is made from LEGO slides (6 x 12 x 8 studs, 11267). It works very reliably and does not jam. There are some more photos over at Flickr.
