- Purpose of use
- As the previous comment stated, this was used to find the circular radius of the USPS Medium Tube (which ironically is a triangular prism) for the purposes of shipping items of circular cross-section (cylinders). The answer was about 1.5 inches, so the "tubes" are way too small for the items I wanted to ship inside. But that''s perfect for blueprints, its designed application.
