Feel like a puzzle? Simple Marble Run v1.0.9

Edit: A new version of this design has been created to no longer need additional hardware (plus other improvements!) Simple Marble Run v1.1.6 (No hardware required)

I originally posted this:

I still don’t have the instructions written up, but if anyone is interested, here is the SVG. I designed it to be printed on Proofgrade Medium Draftboard (12"x20").

Simple Run (v1.0.9)

It is still a work in progress as I learn new tricks and methods.

And it does currently require extra hardware that is not printed:

  • (2) 1.25" #8-32 Machine Screws
  • (3) #8-32 Machine Screw Nuts
  • (4) #8 Washers (for spacing on the wheel axel – 1 in the back, 3 in the front)
  • (4-8) 1/2" diameter Chrome Steel Ball Bearings

(Be aware of those tiny pegs at the top! They fell into the crumb tray the first time I printed them. They are used to pressure fit some of the rails to the ramps.)

If you get it working, please respond back here! I would love to see and hear about your experience!

Wow, thank you so much! I wasn’t planning to use the GF today, but you might have just changed my mind.

How thick are the sheets you planned this for? It looks like you used 1/4" PG draftboard to make yours, is this correct?

It is actually 1/8" Proofgrade “Medium” Draftboard that I used (and it is designed for).

Thanks for the quick answer! I can’t wait to try to piece the puzzle together.

Be sure to use the previous post for reference. It should help with the pictures and descriptions.

OH!! Beware those tiny pegs at the top! They fell into the crumb tray the first time I printed them. (They are used to pressure fit some of the rails to the ramps.)

If anyone has any questions, or runs into any issues with these designs please let me know. I am actively modifying these files.

The latest update has modified the pegs to pressure fit the ramp to rails. I found them very difficult to install initially.

I will update the original post!

So far so good.

Had a rookie mistake though, I did not have everything aligned right so one section and a few other pieces didn’t cut. I removed successful pieces, then did my best to align the remainder. It worked out ok.

Now on to assembly

I just cut everything, and now I return to find you’ve deleted all your pictures. :frowning:

More of a puzzle than I bargained for…
