Engineering Quick Tool: Free Body Diagram

Inspired by Jan Štech and their Template For Electrical Diagrams, I have made a similar design to print for creating consistent Free Body Diagrams, as well as consistent Beams for strengths. 

Designed to be printed at a .2mm layer height.

This stencil contains a ruler (shorter gradations are 1/8 inch, longer are ¼ in), a 45° angled corner, an Axis set (X, Y, and O to denote locations), a pinned connection marker, a beam (and a square body), a simply supported connection, an arrow (for Forces!), a Moment arrow, and circles for either bodies or rolling connections!

This is meant to perfectly fit .7mm lead from a Bic Pencil, but I have included a larger version that fits Pens / Pencils.
