2-Color Recycling Logo

I wanted to print a recycling logo to stick on my garbage can. https://www.thingiverse.com/thing:1376763 looked good, but I wanted a two-color version, so I remixed it using OpenSCAD. Fortunately, in the original the base and arrows are exactly 3.00mm and 2.00mm respectively, which made this a fairly easy remix.

*UPDATE* Reduced the depth of the embossed arrows. No need for them to be as deep as they were.
