Nostalgic STEM play: the construction toy you loved, now 3D printed

Remember those awesome straw construction sets from the '80s and '90s? This 3D print file brings that magic back—but way better. Instead of being stuck with boring cubic grids, you can print vertex connectors with any number of spokes you want. Snap in regular drinking straws and build geodesic domes, tetrahedrons, or whatever wild geometry your brain dreams up. Perfect for tinkerers, parents, educators, or anyone who wants to turn a pile of straws into engineering playtime.

The design is fully parametric and Customizer-compatible, so you can tweak spoke counts, angles, and flatness without touching a line of code. Originally shared on Thingiverse, this tried-and-true design has been helping makers and kids escape the tyranny of right angles for years. Print a handful of different connectors, raid your kitchen drawer for straws, and let the building begin.

You'll receive the STL and OpenSCAD source files, ready to slice and print on your home printer or at your local makerspace. No supports needed for most orientations, and they print fast so you can crank out a whole construction kit in an afternoon.
