Fully Printable Trapped 2020 Hinge

thingiverse

This innovative hinge features a joint design that is exclusive to additive manufacturing, making it impossible to replicate using traditional methods. Its dimensions are specifically tailored to fit seamlessly on a 20XX-style extrusion, allowing the pivot point to sit perfectly next to the outer edge and rotate a full 90+ degrees in either direction. It boasts M3 holes for mounting, which typically emerge as 2.5mm diameter during printing, rendering them suitable for tapping to M3, reaming to 3mm, or utilizing as-is with #4 wood screws, depending on the available hardware and attachment requirements. Two versions of the hinge are offered: a standard tolerance version featuring ~0.2mm clearance in the trapped joints, and a looser variant boasting ~0.3mm clearance in the trapped joint. A printer calibrated to precise standards should effortlessly produce the standard version, but if a fused joint or overly tight movement is encountered, the looser version can be attempted as an alternative. The hinge's structural integrity is contingent on the material used for printing; however, when printed in PETG, it exhibits remarkable resilience, remaining unscathed and unblemished to the naked eye. Consequently, it should suffice for most non-load-bearing applications.
