For me, the hinge works great if you want something strong and friction free.  I was worried about it coming apart too easily which was not a problem.

Of course, like you, I wanted friction which was a problem. Now I'm thinking about adding some kind of ratchet mechanism.

Depending on what your personal settings are, you can increase the overhang angle quite a bit. I have a friend who can finally print horizontal cylinders starting at 80 degrees and he's thrilled.

Great project! The kind of thing were people just need to measure a few things to adapt to their own car. (Or if you're really ambitious, you could model up iterations for the most common vehicles!)

It was a good manufacturing lesson.  Rounds are good with "subtractive manufacturing".  Chamfers work better with "additive manufacturing"

Below is a project I dd with my SolidDoodle on the Local Motors site (open source automotive design).  It was really more of a learning exercise on a few things:

  • ABS (and warpage and rafting)

  • PLA.

  • Press fit and friction (or lack of friction with PLA)

  • Doing something practical instead of desk ornaments

  • Best design for overhangs

I need to better design the assembly to get a bit more rigidity but it basically works.

The project:
