For working carpenters, the speed square is an indispensable tool. It’s handy to checking beams for square, scribing lines, laying out angles, and can even double as a straight edge to guide your circular saw cuts by holding it against your fence.
Most carpenters wear a belt of some kind that holds all their frequently used tools, but most of these tools have a standard shape and form factor that fits easily in standard pockets. However, one of the most used tools, the speed square, just does not fit in any standard belt.
The best solution I have seen to this problem is by the brilliant and talented Tom Silva from the TV show This Old House. I attempted to replicate his design with a quick prototype to gauge the rough dimensions I would need. Download the sketchup model below from 3d warehouse and make your own!
