This project was inspired by ( 3D Printable Vertebranium Headphone Stand by Clockspring (myminifactory.com))
Designed this using inkscape. Still need tweaking to cater for the angle tolerance in the hinges, but overall, I am quite happy with the outcome 
Very clever application of hinges and something designed to be 3D printed to wood and a

Nicely done!
Is. It the angle tolerance that gives it its rigidity after being unfolded?
Impressive
This turned out great! Very impressive.
The hinges are designed to allow each section along the main arc to fold to 30 deg in one direction (stand mode) and 90 deg in the other direction (fold up mode), but the minor slop in the hinge allowed approximately an extra deg. In the fold up mode that does not matter, but in the headphone stand mode, it caused the final hanging part to be too low. I super glued a small piece of material to one of the hinges at the bottom of the main arc to make up for all the slop. In the next revision, I will add perhaps half a degree of constraint to each hinge so by design it can fold to 29.5 deg instead of 30.
Wow, this is extraordinarily cool!
Neat project!
That’s so cool. It looks like a wood version of the drag chain in our lasers.
Very nice! So friction maintains the selected angle? Any worry about losing friction with extended use?
Thanks!
The angles are controlled by the stops designed into the hinge, so they can fold to 90 degrees in one direction (for folding up) and either 30 or 0 degrees at the other direction (for stand mode).
Oh now I get it, two positions and smooth movement otherwise!
Wow. This is so clever!
