Double Helix Tower LEGO GBC Module

Posted by on May 22, 2016 in LEGO | 2 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.

  1. nice module, any instructions

  2. Not yet. The helix ever to slightly violates the LEGO system and hence I could only start modelling it in Stud.io. When I have some spare time I will get back to it.
