Modified a couple framing squares, for use with Maker Pipe joints on an upcoming project.
One square left at 16" x 24" while the other was reduced to 12" x 16", and meant for keeping on square while building up Maker Pipe projects.
Added simple black 'tick' marks (at 2" inside joint, and 3" outside joint) with a Sharpie, for quick visual to ensure full pipe to socket engagement.
I used previous project to mock-up and ensure proper clearance to the Maker Pipe fittings.
