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...
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.
This fraction teaching tool I have designed is called the Fractionator. Simply rotate the discs, and read off both the smaller, and the remaining fraction. Good visual guide to teach fractions. You could also use this as a starting point for teaching equivalent fractions.
Rubik's Cube. 3 plates easy to 3D Print. I used orbital gears instead of circular(sphere not rings). I believe that the movement will be more soft and flow. Very strong pieces. You can help me to do more things like this. Buy my designs at pinshape. The OpenSCAD file is there, you can change all.
Ultimaker 2+ recommendation: 0.2mm layer height, 0.4mm line width, 0.8mm wall thickness, enable Alternate Extra Wall, 25% infill, skirt
Golden Ratio Seahorse Gears. Animated GIF: Inspired by Nautilus Gears by MishaT: I added a new smooth running seahorse gear version (v3). The new version does not latch into a closed position and is suitable to drive with a motor, etc.
Want to impress you friends? Print out these weird looking gears for them! they will love it. Scale all 3 parts down by 50% Print them solid at 0.1 - 0.2mm layer height Lock the gears in place and spin the wheel! Have fun printing!
Ultimaker 2+ recommendation: 0.15mm layer height, 0.35mm line width, 0.7mm wall thickness, 15% infill, skirt, 50% scale. If you break the pins, enlarge the holes and use 2 M3x12 screws with nuts.
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.
Marblevator "Mini", Counterclockwise Hand Cranked Base by gzumwalt
If you wanted to build the Marblevator "Mini" series but hesitated because you didn't want to buy motors, connectors, power supplies, batteries, etc., and then have to solder the whole mess together, then this thing may be for you.
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.
The pantograph is the original scaling tool! It was first developed in 1603 so that Christopher Scheiner, it's inventor, could copy and scale diagrams with great precision. Something we now do in seconds with copy machines and computers was done entirely by hand back in the days of old.
This podiatric model can be used to study the skeletal compostion of the anatomy. The model is made in two parts, the left foot can be removed from the base and inspected seperately, while the base can be used as a mould to cast the impression of the foot.
Homo Naledi Skull Reconstruction - Lower Face by dricketts
Named Homo Naledi, this new species of an extinct early human ancestor discovered by the Rising Star expedition team near Johannesburg, South Africa has stunned the paleoanthropology and archaeology world, and in true scientific fashion, they have published scanned specimens of their find and published on http://www.Morphosource.org for all to enjoy and participate in this extraordinary discovery.
This is a skull with a story, and you can listen to it right here: http://www.radiolab.org/story/taung-child/ Radiolab worked with folks at MakerBot and the Field Museum to get this thing scanned. The scan was refined and made more detailed (and more badass) by shootdigital.
Right hemisphere of the brain of Rajat Jain (25) obtained with an MRI scan and used in UCSF's and UCSD's glassbrain project.

This is a model of Gale Crater, where the Mars Science Laboratory Curiosity is roving around and blasting holes in the landscape. It's 1:1925000 scale. The Curiosity Rover would be about two microns long, or about the length of one E. coli cell.
This thing is a bump mapped sphere that uses the planetary map data/images from [link=external="http://www.johnstonsarchive.net/spaceart/cylmaps.html"]johnston Archive. Specifically, I used this one: I essentially used the same bump mapping technique I used on this bowl. That is, use the picture as a height map.
As a single coil 3d printed pulse motor, it has very little torque, and is basically useless except for science fair projects and bragging rights, but it is fun to assemble, fine tune, and test. Video of prototype.
A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup that forces its user to imbibe only in moderation. Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level.
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.
Ultimaker 2+ recommendation: 0.2mm layer height, 0.4mm line width, 0.8mm wall thickness, 0.6mm solid_layer_thickness, 0% infill, set solid_top to False, set solid_bottom to True. Read through the instructions and explore Peetersm's G-code.
I bring you the 3D printed, 8bit character, rubber stamps! With included 3D printed handle. These stamps are quite big at 55.7mmx55.7mm (2.2inx2.2in). We have designed the stamps in such a way that you can have one stamp handle and change the rubber stamp design to the one you like.
Ultimaker 2+ recommendation: For stamp part use flexible filament. 0.2mm layer height, 0.4mm line width, 0.8mm wall thickness, 15% infill, skirt
This design turns your bike wheel into a zoetrope!* It was designed for 18 spokes (on one side of the wheel. There should be 36 spokes altogether), with two cycles of the full animation. The files included are robotbody 1-9, and two sets of clips to attach them to the spokes; one for 3.5mm wide spokes, and one for 2mm wide spokes.
The inspiration here is threefold: After seeing the awesome sculptural work being done on the pet monster contest, I knew I wanted to try my hand at organic modeling and I wanted a way a cool way to incorporate it into a 3D print.

New Year new intentions...! This year i will upload a new cup every week. This is number one...! Done in Blender, which was quite difficult for me to figure out how to get this pattern on the cup. The trick is displacement mappings and a lot of persistence, but then you can create the most beautiful objects.

Love playing card games or know someone that does? This makes a great gift for anyone with dexterity challenges, the elderly, as well as kids. Cardeasy helps hold and organize a hand full of cards and if you print one out for someone that has that problem, they will love you for it.
This is my second try at a one piece hinged box with latch. This latch is a little easier to operate than my box design I derived it from. For more information about this box, see the box it was derived from. I like this latch design a lot.
Girih Tiles for Interactive Islamic Designs by mathgrrl
3D print and assemble your own classic Islamic-style artwork by using Girih tiles to build intricate woven strapwork! The tiling pattern in the photo is rotationally symmetric. On the left are the basic colorful tile shapes. Towards the middle we have started to add the overlaid strapwork, which is completely determined by the tiles.
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.
