A simple, easily customizable template/stencil for drawing graph axes. Perfect for graphing functions in high school math classes, or wherever else you may find it useful.

The original version, graph_1.5_in.stl, prints in about an hour with standard settings. This file has a 1.5 inch (38.1 mm) long pencil track on each arm. The track is 1 mm wide, which accommodates a well-sharpened pencil or standard mechanical pencil.

The other file, graph_1.5_inch_wider.stl, has wider 1.5 mm tracks. Use this if the tracks are too narrow even after sharpening your pencil. It may also fit a ballpoint pen.

I've included the .scad file, so you can easily edit all the dimensions of the template using OpenSCAD or the Customizer app on Thingiverse (although Customizer is broken at the moment).
