I used to love marble runs when I was a kid.
I started designing parts to print and realized that,
1: They're Huge
So I decided to design smaller pieces in a effort to make a desktop friendly version.
2: They require supports
So I decided to design them with integrated supports that look good (I hope).
These pieces use 4.5 mm BB's available in any sporting goods department (Metal is better).
Print as many as you like. The all interconnect and are pretty fast prints.

If you want to design/add your own parts I'd recommend starting with the Pillar file as your base.
NOTE: Because the scale is so small the BB's do sometimes jump the track. Makes for a good reflex test :)
Have fun! Please post pics/videos if you print/remix!
