Print-In-Place 7.5° Click Adjustable Drafting Triangle
This adjustable set square prints as one piece. A 94 mm drawing arm swings from 0° to 90° on a captured bicone pivot and clicks into a detent every 7.5°, so it holds 15°, 22.5°, 30°, 45°, 67.5° and the other common angles. The 128 mm straight base edge rides along a T-square or parallel bar, and the 6 mm frame has engraved tick marks on the rim every 7.5°, with a longer tick every 15°. The arm's flexure finger works without screws, inserts or other hardware.
