This is Day 11 of my collection of printable equations. To see the whole collection, go to: http://www.thingiverse.com/thing:227210 Based on plastic's request in the comments, (http://www.thingiverse.com/thing:231587/#comments), for today's equation, I'm doing y = sin(cos(x/7)+sin(x))*x. I've included the Openscad file in case someone wants to modify the text or stand. Details: As always, I'm going to continue 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.All files can be printed without support. Photos shown were printed on a Replicator 2 and sliced using the standard setting on Makerware.
