This is Day 1 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210 I thought I'd start off with a classic sin function. Two full periods shown. Details: I've always been interested in different ways to visualize and explore data. I thought it would be cool to try to print 3d representations of equations. The graphing libraries I could find weren't flexible enough for what I needed, so I wrote a Python program to take an equation and plot it in Openscad using the polygon command. The 3d equation is mounted on a stand that also displays the text form of the equation. I'm going to post one equation per day until get bored or people lose interest. If there's a particular equation you'd like to see, leave a comment and I'll give it a shot. Technical Note: All files can be printed without support. Photos shown were printed on a Replicator 2 and sliced using the standard setting on Makerware.
