The file 'String Monorail Car Thing 3D Printer Model' is (stl) file type, size is 9.5KB.
A while back I made a string monorail car type thing with an Erector set and a piece of wood. I happen to have found it in one of my old storage boxes. It didn't run reliably on a sloped line and was too heavy causing the line to snap if i tightened it enough to keep it from bending downward (darn gravity).
So I decided to pop open the Sketchup and design a replacement.
