cults3d

The 3D Models included in this download are three different DROP TRACKS; Short drop 28x75mm, Long drop 28x150mm(not shown in pictures), Huge drop 105mmx150mm and also includes the track clips which hold them together. 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.
