Looking for a super compact LEGO Great Ball Contraption ? Meet the adaptation of the Brickworld 2017 Workshop module designed by qrti! This German LEGO designer has created free building instructions to reproduce an alternative version from the LEGO GBC proposed to some lucky participants to Brickworld 2017 edition (and initially designed by Bryan Bonahoom). Kurt “Qrti” used LEGO Technic bricks to build his marble run machine whose mechanism is relatively simple but smart in design. A platform is oscillating up and down, collecting GBC balls once down and expulsing them when up. Some LEGO Technic liftarms are preventing the balls from going underneath the rotating platform when up. Small but powerful, and ready to be built with your kids.
