Print it yourself at https://oskarvandeventer.nl/Print-It-Yourself/. #shorts Heron's Fountain is a classic water ornament, powered by gravity. The water is pushed out by air pressure from water leaving the top container and going into the bottom one. This version is 3D-printed as one single piece. Will you 3D-print one on your own 3D-printer?

$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.
