Square Tube Miter Template — 2" Square Tube, 45° Cut Wrap

Printable wrap template for a 45-degree miter corner in 2in square tube. Developed from the square-tube unfold: wrap width = perimeter 4 x 2.000 = 8.000in, cut at 22.5 degrees for a 45-degree joint, wave amplitude = 2.000 x tan(22.5 deg) = 0.828in peak-to-peak by trig. Faces 1 and 3 are flat (parallel to the bend plane); faces 2 and 4 ramp. Print at 100%, wrap around the tube with the seam on a corner edge, trace the heavy line, cut on it — two identical pieces make a 45-degree corner. Grip margin 0.75in above and below the cut line. 2.00in print-check square included to verify scale. True 1:1 scale at 96 DPI. Pure geometry — no vehicle fit involved. Works on the outside of the tube, any wall thickness. Test-fit on scrap first.
