Markus Ball is a variation on a puzzle design by Markus Goetz. Markus' original design was a 2x2x2 cube, built from four parallel 1x1x2. Markus' challenge was that opposite 1x1x2's were connected. So how can such a puzzle come apart? Here is a modified version of this puzzle, turned into a tennis ball. Markus Ball is an easy fun puzzle. It has eight 3x3-mm cylinder magnets to have it click together.

$Fractional Gears - How can a gear have half-fold rotational symmetry? Print it yourself at https://oskarvandeventer.nl/Print-It-Yourself/. Buy at https://i.materialise.com/en/shop/item/fractional-gears or at https://www.shapeways.com/product/AC524R66H/fractional-gears Fractional Gears is a gear set that features a gear with half-fold rotational symmetry. A gear with 180-degrees symmetry is said to have two-fold rotational symmetry. The green egg-shaped gear has 360-degrees one-fold symmetry. For a 360-degrees turn of the green egg-shaped gear, the smaller red gear rotates by 720 degrees. Following the earlier naming logic, this gear has half-fold rotational symmetry. In order to make the cardioid-like gearing, the red gear has two layers. The teeth pattern continues from the bottom layer to the top and back to the bottom. In order to fit the bigger red bottom, the green gear has a cut out to make things fit. Copyright (c) 2023, M. Oskar van Deventer.
