Square-to-Round Transition Template — 1.5" Square onto 1.5" Round

Printable flat-pattern template for a square-to-round transition: 1.5in square onto a 1.5in diameter round, transition length 3.00in. Developed flat pattern by triangulation with 12 divisions: pattern width 5.799in, pattern height 4.069in, generator true lengths G0-G11 from 3.001in to 3.016in (all by 3D trig, every developed edge asserted in code), seam on one generator - both seam edges are the same generator line, length 3.016in, overlap and weld. Heavy line is the cut line, dashed lines are bend / triangulation form guides. Top view (1.500in square / dia 1.500in round) and side view (3.00in transition length) on the sheet. True 1:1 scale at 96 DPI - print at 100% and verify the 2.00in print-check square before cutting. Pure geometry - no vehicle fit involved. Works in sheet or plate, any gauge - bend lines are form guides, allow for your material thickness. Test-fit on scrap first.
