Problem Solvers Sketchbook and Bench Reference Guide

The Problem Solvers Sketchbook and Bench Reference Guide exists because writing things down is important. Sketch out new ideas, record findings, workarounds, geometries, spoke lengths, never-try-it-agains, or just to doodle during that boring meeting at work.

- DIY Reference and/or User Manual
- Engineer-ruled for oddball geometric sketching
- Includes semi-useful tables and tools
