This is one of my first designs using Fusion 360. I wanted a hinge that was strong enough to hold a 54 cm door made up of 2020 aluminum extrusion and a Plexiglas pane. The hole for the 5 mm shaft is intentionally tight to prevent the door from sagging (you may need a hammer or mallet to insert the shaft). The hinge should be printed in PETG with 100% infill and "Support on Build Plate Only". With these settings the 54 cm long door only sags about 3 mm.
