Marble Rollercoaster

This parts are working on my Ender 5. The clips are working quite well with my 1,75mm filament. I used old wire hangers to connect the rails to the build plate. It works with 25mm marbles.

Note: The filament broke after some weeks beeing under tension. It may be worth to use some other 1,75mm material or some less brittle filament..
