The file 'Roller Coaster 3D Printer Model' is (stl) file type, size is 3.1MB.
I like gears and thought it would be cool to have coasters with a set of gears inside. Everything snaps together nicely without any post printing work and the gears spin freely.
The coasters can be taken apart to clean if needed or even glued to be permanent.
