Description
A marble run system for 11mm ball bearings.
Please see the Starter Set for a full description, photos, printing notes, and links to the complete system.
The rail block was designed so that the rail bottom is printed flat on the build plate. Supports are required only for the top and bottom ends of the rail.
Each rail block filename (railv5_NNxM.stl) indicates the length (NN) in studs and the vertical drop (M) in bricks.
A new version of the rail block may be forthcoming that attempts to use as little material as possible. Stay tuned!
