Not to worry! You can use a 3D printing service such as 3DHubs or MakeXYZ to have a local 3D printer operator 3D print and ship you parts to you. This is a great way to get your parts 3D printed by local makers. You could also try checking out your local Library or search for a Maker Space.
The tracks are fully 3d printed and designed by Tulio Laanen – It uses a worm style elevator to lift ball bearings up the tracks. This marble run is an impressive design that is 3D printed in a single part. We design a base to fit the electronics and components. The marble run design can be downloaded from the thingiverse page.

These settings are for a 0.4mm and 0.8mm nozzle profiles using CURA 3.4.1. Optimized for the Ultimaker 2/3.
The motor bracket will require supports because of the way the standoffs mount to the Circuit Playground Express and the Crickit.
We recommend adding a interface layer to decrease supports from fusing to the part. Breakaway filament is very handy in this application, since it will not fuse and won't distort our part.
Below are links to modify the design of the enclosure, noodle size and motor parts to fine tune them to adjust to your printer tolerances.
The enclosure assembly was designed in Fusion 360. This can be downloaded in different formats like STEP, SAT and more. Electronic components like the board, displays, connectors and more can be downloaded from our Fusion 360 CAD parts github repo.
