Polyhedra
Customizable Convex Polyhedra by pdragy
openSCAD database of all convex polyhedra with regular faces except for prisms and anti-prisms. This includes the Platonic, Archimedean, and Johnson polyhedra (over 100 total!).

Pictured are all the Platonic solids and a few Archimedean solids created with the customizer.

Tetra
Tetrahinge by mathgrrl
The hinges are built to print together, fully assembled, using the "low" setting on a Replicator 2. What I'd really like is to have modular faces that you clip together after printing, since then I could make much larger polyhedra. Maybe another day...

Math Gears
Math Gear(s)by SSW
This Math manipulative is designed to appear playful from the first look. It lies flat on desk top, so it will also work well with overhead projection systems.

Behind the mechanical fun there are several simple ratio exercises. The eight tooth "Idler" gear is supplied to add reverse rotation without affecting the ratios. Each interchangeable gear has built-in graphics to indicate the number of teeth as well as rotation position. Some gear ratio formulas can be found here: Wikipedia.

Rubber bands provide tension to keep the wheels engaged no matter what the combination.

Math Spinner by FunFunBoy
My 4 old kids start to learn about math operation so I search something to make math more fun. Found "Math Spinner" from Math Spinner Enhanced (fast print, no support) is very interesting.

So I made my own "Math Spinner" with angle step lock so It doesn't freely rotate.

But with the center to print so everything made ​​in 3D!

Clebsch diagonal cubic surface by larum
ALFRED CLEBSCH Rudolf Friedrich Alfred Clebsch (19 January 1833—7 November 1872) was a German mathematician who worked with algebraic geometry and invariant theory. He collaborated with Paul Gordan on Clebsch—Gordan coefficients for spherical harmonics, which are now widely used in quantum mechanics.The Clebsch diagonal cubic surface, or Klein's icosahedral cubic surface is a cubic surface is a well known form, all of whose 27 exceptional lines can be defined over the real numbers. This is a a representation of Clebsch's diagonal surface.

Propeller & Spinning Top Launcher by tigermcho
This launcher is designed for both of propellers and spinning tops. You can fly the propellers and also spin the tops by using one launcher. It is a new design, but it was inspired by Davidcolsson's propeller launcher. To fly the propellers and turn the tops, I also adopted the Davidcolsson's method of pulling a dragger.

drooloop flowers by peetersm
These are really fun to design and print. Each print job is fun since there's a slight element of randomness. The randomness is because we are deliberately "printing in the air" to create the "drooloops" (droop+loop) that make these flowers look so amazing. I have uploaded both openscad design file AND the gcode files for ten different flower shapes that you can download and print right away. See Breaking Barriers in Education with 3D Printing.

Sundial
Digital Sundial by Mojoptix
No batteries, no motor, no electronics... It's all just a really super-fancy shadow show. The shape of the sundial has been mathematically designed to only let through the right sunrays at the right time/angle. This allows to display the actual time with sunlit digits inside the sundial's shadow.

The sundial displays time (with actual digits !!) from 10:00 until 16:00, updating every 20 minutes.

You can precisely adjust the displayed time simply by rotating the gnomon (the magic box that displays time). So you can even adjust for Daylight Saving Time.
