This is a set of modular marble track pieces that work well with 3/8" bearings (or other similar, small marbles.) By default, the track "unit" is 20x20x20mm; the open pieces of track are half-height, and the drops are double height. Print it out and use it (like I have) to avoid whatever important work you're supposed to be doing.
- the OpenSCAD file (which is parametric, and should work now),
- two track set STL files (which are about 160x160, so should print on an i3)
- individual STL files for each piece in the standard sets
- an 8mm marble (which probably needs a raft/brim, and may not be heavy enough)
Updated on 21 Apr 2017: The .scad file now has better support for parametrization; if you use Thingiverse's customizer, you'll get a full set with one of each piece, which should make changing/remixing easier. I also squished the pieces together a little more in the track sets, which should reduce print time a little.
Prints well at 40mm/s and .3mm layer height on my cheap i3 clone. The pieces have (by default) .25mm of extra lateral room at the connectors; if your printer is nicer than mine, you might need to change this in the OpenSCAD file and re-generate the pieces / track sets.
