Hollow Triangular Metric Architect Scale

A 160 mm triangular drafting scale with four engraved metric edges: 1:20, 1:25, 1:50 and 1:100. Each edge has 140 mm of tick marks. Each scale starts at a 1–4 pit code at its zero end. The body is a hollow 36 mm equilateral tube with 3 mm walls, so it stays light and prints apex-up with no supports.
