About this 3D model

This is an addictive puzzle-game for your desk. It is a 100*100*100 cube with a secret pattern inside. You start by putting a ball in the hole and try to follow the pattern untill the end. It is best played with a bucky ball (magnet ball) of diameter 5mm, but any ball smaller than 10mm can be used. 3 designs to cover 3 difficulty stages. Challenge yourself and try not to look into the pattern for the 'really difficult' puzzle (if you can...) 'Make Anything Design Challenge'
