The 3D Models included in this download are 9 files which make-up the manual START LINE; Start Line box has two options (3 files), for small print beds, it can be printed in two pieces or a single piece for larger print beds. This connects to two standard straight tracks (150mm not included). The start line includes an integral track clip which holds two pieces of track together. This start line gate holds up to 20 racing marbles in place. Some assembly is required. Two small rubber bands will need to be added to the start line gate, a filament hinge will need to be installed which holds the start line gate in place on the start line box. A small piece of filament is used as the start line pin and once removed will release the racing marbles. See the photos and video above. A marble racetrack is different than a marble run. The race track is wide and allows multiple marbles to race side by side instead of in a straight line like most marble runs. This allows you to race the marbles and see which marble is fastest. Each marble is unique in size, weight and roundness. This makes for some interesting marble racing. Want something fun to do with your family and friends? Try marble racing!
