Seven Gear Loop

Seven Gear Loop is a gearing mechanism of seven gears in a loop. Usually, a loop of gears requires an even number of gears, as otherwise the loop gets stuck. After all, the gears should turn alternatingly clockwise and counter-clockwise (anti-clockwise). However, it works for this gear set, as the seven gears are not in the same plane.
