A remix of the popular Parametric Butt Hinge by rohingosling, that adds more customization options.

Changes:

• Allows 1-rows of 2
• Allows placing 1-rows on the edge, like 2-rows (there's no point in having leaf length past the screws when holding vertical doors)
• Supports setting different leaf sizes on both leaves

Open the file in OpenSCAD to pick settings and render (F6) then export to STL (F7) (or CSG), or edit directly in thingiverse's "customizer".
