This model is featured in figure 3.12 of Visualizing Mathematics with 3D Printing . Video . Stereographic projection is a map from the sphere to the plane: Imagine straight lines going from the north pole of the sphere down onto the…
After a long search, I managed to make a 3D printed stereography sample. The three-dimensional cube can rotate when you rotate the position of the observer, light source or object. This project is inspired by the work of the Russian…

The model can be resized, mine has 15 cm of diameter. It can hold a candle and the projection will change as the candle gets smaller. I can make custom projections! Send me a message and we can discuss it. Print Settings Supports: Yes…
This design was inspired by henryseg's Stereographic projection. I fell in love with the Hilbert curve and after seeing what Henry made I decided to make my own projection. Print instructions Category: Math Art Summary This design was…

This little gizmo is used to view stereoscopic images on a postcard-sized printout. The centers of the two images should be 64mm apart for optimal results (that's the interpupillary distance this was designed for). The lenses I used were…
This is a lamp that projects a hexagon pattern on the ceiling (or floor), created entirely in openSCAD. The pattern is customizable within the openSCAD script, and I've included an example of projecting squares. Parts: shade (printed)…
I made a customizable version of henrysegs ingenious design that uses stereographic projection to project a grid from a sphere to a plane: http://www.thingiverse.com/thing:202774 You can simply upload an image with the size of 75x75 and…
If a single point light is placed near the North pole of the sphere, a grid is projected in the shadow.
Stereographic Projection based on the excellent work shared here: https://jasmcole.com/2014/11/01/stereographic-lampshades/#more-650 I used Blender's "Solidify" modifier to add various thicknesses to this model for printing. I recommend…

Created locally with: http://www.thingiverse.com/thing:1216198 and this script: http://jsfiddle.net/threonin/6dr8qu41/ It is 500x500 pixels, but finished while I was watching a movie, so it seems the script got much faster when I changed…
Highres version of http://www.thingiverse.com/thing:2078413 This allows using pictures with 85x85 pixels instead of 55x55, but it is also considerably bigger. I used these 10W power LEDs, here they come bundled with drivers:…

This slides over a Mini Mag-lite 2 AAA LED flashlight to project an 8x8 checkerboard pattern. This is demonstrating stereographic projection. This can project huge squares of light across a room and is fun to play with, especially when…

A newer, actually printable version is here: http://www.thingiverse.com/thing:1922547 I modified the script to support simple halftone dithering, so each pixel can have a gray value between 0 and 1, the brighter the pixel is, the bigger…
This is basically the same as http://www.thingiverse.com/thing:2191384 only it has the ability to insert a LED with a cooler. It will be located in the jaw directly at the north pole of the imaginary sphere. These are the coolers I used:…

Basically the same as http://www.thingiverse.com/thing:295281 but the form is no sphere but is flattened to some kind of mushroom shape. The customizer takes 75x75 images, but you must be very careful that no diagonally touching pixels…
By changing the resolution back down to 55x55 pixels I can actually slice the skull in Simplify3D! Printed fine without any tearing, it was probably due to the way too thin walls at 85x85. It is by default scaled to 88%, the lowest it…

Again big thanks to Joe Balint for suggesting to simply remove the corners for easier printing! This way I was able to crank the resolution up to 100x100 pixels and have it still sliceable in Simplify3D! Make sure to have no important…
Big thanks to Joe Balint for coming up with the idea to use a skull for the stereographic projection! I modified my script to create a difference from a hollowed out skull and the projected picture, so adding a light in the correct…
This is basically the same as http://www.thingiverse.com/thing:295281 but with just 75x75 pixels instead of 150x150, this works in customizer just fine, maybe the highres version will work later, I filed a bug report for customizer. If…
