Point Break Desk Toy

Point Break - Desk ToyI am happy to share the Point Break Desk Toy, a stylish and mesmerizing addition to your office desk, or a physics toy to put anywhere in your home. Point Break visualizes rotational motion by transferring movement through interconnected mechanical components. It demonstrates the conservation of rotational motion and how energy is transmitted, making fundamental mechanics easy to observe and understand. This self resetting rotational chain reaction mechanism creates a moving wave and has been named ”Point Break” after the location where waves break when hitting land. (Originally this toy goes by the name Xylo by David C. Roy.)The model is available in 2 different versions (”100% printed” and ”Ball bearings”) and 2 different sizes (8 pieces and 12 pieces). In my opinion, the 8 piece desk toy is a nice and reasonable print while the 12 piece is more impressive but quite large. The ”100% printed” works very well and is easier to assemble. However, it does have some wobble in the X-axis. In contrast, the ”Ball bearings” version (which requires 8 or 12 “605ZZ” or other bearings with an 14mm diameter, 5mm hole and 5mm thick), is more work to assemble but locks the rotating pieces in the X-axis and creates a much smoother, stable and satisfying movement.   Printing4 print profiles are available (100% printed – 8 pieces, 100% printed - 12 pieces, Ball bearings – 8 pieces, Ball bearings - 12 pieces). The print profiles include a modifier to add a second colour to the rotating bars.There should be no issues printing the pieces needed for this model, except for the fact that the long shape of most pieces might make them prone to warping. In addition, the small ”spacers” for the ”Ball bearing” version has little contact with the bed, so overall good bed adhesion is recommended. The bar holding the rotating pieces will be under a light constant load, and I have noticed that for the large ”12 piece version”, PLA will start creeping (bending) relatively quick
