Square-to-Round Transition Template — 2" Square onto 2" Round

Printable flat-pattern template for a square-to-round transition: 2in square onto a 2in diameter round, transition length 4.00in. Developed by triangulation with 12 divisions - pattern width 7.732in, pattern height 5.426in, generator true lengths 4.001in to 4.021in (every developed edge asserted in code). Heavy line is the cut line; dashed lines are bend / triangulation guides; both seam edges are the same generator line (4.021in) - overlap and weld. Top and side views on the sheet. True 1:1 scale at 96 DPI - print at 100% and verify the 2.00in print-check square measures exactly 2.00in before cutting. Pure sheet-metal 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.
