Sliding Door Rail System

thingiverse

Print as many rails as you need for the length, with each one requiring two end caps. A middle hanger will run along these rails, but it won't rotate - it'll just slide smoothly in place. To accommodate this setup, position the swivel hanger at the rail's end so that when you pull out the door, it can swing freely to one side. Going forward, I plan to add a special cap to allow the linear hanger to slide outward while keeping the swivel hanger firmly in place.
