A double-revolute joint which serves as an elbow joint.
Consists of three parts; Alpha, Beta and Charlie.
The 'Alpha' and 'Charlie' parts are both designed to slot over the end of 20x20 aluminium extrusion.
Of course, if you have CAD software like Fusion 360, you can modify the .STL files of both these parts so that they will fit whatever you like.
The 3DP nut and bolt in this joint have been adapted from

However, they are pretty weak. Especially if only printing in PLA.
Don't over-tighten or the top will snap off the bolt.
It's a good idea to use 25-30% infill at 0.15mm resolution for the main parts of the joint, then use finer 0.1mm resolution and 50% or higher infill for the nut and bolt, to give it a well-defined thread and ensure that the bolt is as strong as possible.
For my own model, I intend to replace the 3DP bolts with proper steel ones.
