Excellent work! I especially appreciate that you did the step-by-step process with "found" materials, but also included a 3D-printed version. Well done.

Excellent Instructable! I really like the idea of the drill guide. I'm a maker of marble runs, too, and have made a magnetic run using a drywall J-trim that I found at my local big box hardware store. However, now that I have a 3D printer, I need to give yours a try!
The pegboard is standard 1/4" holes on 1" centers. I think the piece here started life as a 24" x 48" piece from the big box store, but I cut a piece off the end for another project, so the finished size is 24" x around 36".The feet (actually 10" long peg hooks inserted upside down on both the front and back) keep it from falling, although there is a little "springyness" to the whole assembly. It can bounce a little, but it won't fall over.
Excellent! Very well done. You've inspired me to try this myself.
Thanks for presenting this. I made my version over the weekend, using a piece of pegboard as the back and some 2-prong 4" pegboard hooks to hold the cups. I then added a small pump with a switch to pump the water from the bottom cup back up to the top cup. I think this will eventually become part of a booth display for the Omaha Maker Group, probably with an Arduino and some sort of water-level meter in the bottom cup to control the pump. Thanks for the inspiration!
