LEGO GBC - Squared, by pinwheel

I’m ready to bet you will love the hypnotic moves from the Squared LEGO Great Ball Contraption module from Pinwheel GBC. Inspired from the famous cup to cup module from the legendary GBC builder Akiyuki, this appealing LEGO GBC module is using assembly of LEGO Technic bricks to replace the cups used in the original module (LEGO cups which became super-expensive overtime). But this module is really not a simple copy, it comes along with several excellent building ideas, making it a really reliable build. Thanks to Pinwheel free building instructions, you can even reproduce this elegant LEGO marble run machine and watch the endless rotations from its eleven arms.
