Here is the latest iteration of my Simple Marble Run. This version does not require any additional hardware. (Designed for 1/8" thick material and is designed to be used with 1/2" diameter “marbles”, I use ball bearings.)
Note: When printing on the GF, set the second grouping to “Score”.
General Instructions: (Be sure to use the finished images below for reference also!)
- Put the main wheel together. Be careful not to flip any of the layers, otherwise they may not line up properly.
- Assemble one of the small cross-axles. Insert it into the front of the front structure, and hold it in place with an axle-lock on the other side.
- Assemble the long cross-axle. Insert into the back of the back structure. Install the following on the axle so that it is inside the structure:
A. Axle washer
B. Three axle gears (aligned)
C. Axle washer
- Install the assembled wheel on the front structure axle, and put the two structures together. Feeding the long cross-axle through the front, and install the following:
A. Axle washer
B. Five axle-spacers
C. Axle crank
D. Axle lock
- Install the structure braces. Be careful with the upper braces, they are small and can break easily.
- Install the ramps
- Complete the crank handle
There are several pictures of the original designs you can use to help see how it goes together on the original posts:

No Marbles, no problem!
If you want to try to make you own marbles, here is a pattern that will make the right size:
They are a tight fit to hold together. Insert the “X” into the “round” and twist so the final piece can lock it together.
You will need to fill the openings with wood filler (or some other filler) to ensure they roll properly.
