Manual Start Line for Marble Sports Racing System - A Modular Marble Racetrack Toy

cults3d

The 3D Models included in this download are two files which make-up the manual START LINE; Start Line box which connects to a standard straight track (150mm or longer-not included), Start Line gate which hold up to 10 racing marbles in place. Some assembly is required. A small rubber band 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!
