This is my Second attempt at a modular width track. This set is a center lane ramp with a merge for the tow outer lanes, bringing a 3 lane track to a 2 lane track with a single lane ramped exit from the middle lane. The Ramp rises to 55mm which is slightly short of the reccomended 75mm clearence of a track overpass.However elevating to 75mm in a 240mm length is not exactly recommended. I would recommend using a 20mm single lane ramp as the next track in line. For the two lower lanes you can either use the included modular lanes to bring them back to a 2 lane track section or branch them off to single lane sections.

With this Modular set one would be able to print a track with any number of lanes with only a 256mm by 256mm 3d printer bed. The lanes are 240mm long. The lanes fit together with a left side key and a right side hole. I have not yet done test prints of these files. it is recommened to use blue painters tape to hold the lanes together. It is not recommened at this time to use these tracks in an elevated situation.

The L ending Files are versions of the left, right, and ramp models with slots removed in the center 30mm of the track to reduce filament usage. L for Lite
