Các mảnh ghép Marble Run (Đồ chơi thả bi)

We bought a Marble Run kit from Amazon for the grandkids and I wanted to expand it. Unfortunately, none of the existing models on Printables were the right size. So I designed thirteen parts that could be used with our existing system, but could also be used as a stand-alone system.

These parts are designed to work with 5/8" diameter marbles. Most of the parts are forgiving for marble size. But two, the Pachinko and the Splitter, utilize tight tolerances to create random paths. Larger or smaller marbles will result in non-ideal behaviors.

I printed all the parts in PLA. Supports are required over the entire bottom side of the Pachinko. The Splitter and the Junction just require supports at the top of the wide opening. I didn't use supports on any of the other parts.

Because I designed it to interact with purchased parts, there were constraints on the tolerances. These parts fit really well with the purchased parts as printed, but require a little sanding the fit together with each other. I had to sand the hex post at the top of each part. (Really just knocking the points of the hexes!)

Please note that the photos show a large yellow funnel. That is NOT my part (and is a bit beyond my TinkerCAD capabilities!) If you want that part, you need to buy this system from Amazon:

There are also some other cool parts in the set.
