Slanted Angle Bracket
Built by Richard Marsden in April 2016
A 3D-printed part, designed to hold together the slanting sides of the base of a tower. Because all four sides slant inwards, bending a standard angle bracket to an obtuse angle won’t achieve the right shape; the holes will be out of line. The slant angle is about 16.26° (equal to arctan(7/24)). This because the tower base is built from 7–24–25 right-angled triangles; a different configuration would require a different angle. Note however that more extreme angles will eventually cause a clearance issue, with the bolt heads starting to interfere, unless the bracket is lengthened considerably to allow the bolt holes to be staggered.
