A thrilling Marble Machine that's designed to challenge climbers and offer customizable tracks for an ever-changing experience. No additional hardware beyond the ball itself is needed, unless the optional motor installation is chosen. With only two available tracks at present, more exciting paths are in development. Instructions on building this unique contraption can be found here: All necessary components have been successfully printed using a Printrbot Plus at 0.3mm layer height and 20% infill settings without requiring any support material during printing. Each ball used in this setup is precisely 9,5mm steel balls sourced from: http://www.ebay.com/itm/BALL-BEARINGS-9-5MM-3-8-PACK-X-100-/200970728122?pt=LH_DefaultDomain_0&hash=item2ecac9f2ba Additional upgrades include an optional motor mount and gears to integrate a motor into your setup, or a simple DC connector installation with available components. Specifically, this means integrating the Micro Gearmotor 75:1 rated at 3V (available from Pololu) or a switch-activated Coaxial Power Jack DC connector. Should you require a different approach for powering, let me know if you would prefer a battery box setup instead.
