Making a Steel Marble Track with 3D printed forms

This marble track is made using segments formed using 3D printed parts. I used my ender 3 to create forms to bend the steel wire tracks. I created 4 basic shapes that were bent with the forms, including a 450 degree spiral corner. Once the rails are solder together into segments, track assembly can begin. Each segment is soldered to the last starting at the bottom and working my way to the top! The 3D printed forms were particularly useful for the more complex bends that would have been difficult to get right by hand.
