6mm Brio Tunnel

thingiverse

My interpretation of the Brio train track system. Tracks are only 6mm thick instead of 12mm (to reduce filament usage and print time) with male joints which then eliminates the requirement to have tracks on the reverse side of the bends. There is also 6mm to 12mm ramp so that the printed tracks can also be joined to already owned wooden brio tracks. Track sizes for train wheel axle width = 18mm to 34mm. More models coming - Platform, Seesaw, Turntable, Buffers & Large Bridge.
