The rails are derived from https://www.thingiverse.com/thing:43278
The bearings are inspired by https://www.thingiverse.com/thing:2746804
The gears use the MCAD (involute gears) library which is shipped with OpenSCAD
Make sure the bearings roll nicely and insert the wheels into the turntable gear before putting the gears on the floorplate. Enjoy playing!
