z = theta (Spiral Thingamajig)
thingiverse
Print with raft and supports This one is a fun one. Helpful for Calc students learning about cylindrical coordinates. I suppose it could also be modified to make an ice drill, for if you are interested in ice fishing, or ice drilling. Made in USA (in Mathematica) with following code: Spiral = RevolutionPlot3D[z = theta/20 Pi, {t, 0, 1}, {theta, 0, 6 Pi}, BoxRatios -> Automatic, BoundaryStyle -> Black, PlotStyle -> Thickness[.1] ]
