Adjust an angle of two parts using a predefined amount of steps

• Angle can be fixed using screws
• Using a bolt with a spring would allow the discs to be rotated but would snap them to certain angles (like a wheel of fortune")
• Customizable to make it fit for a lot of purposes

  Shoutouts to the friendly people on the OpenSCAD-Mailinglist who helped me with a difficult issue in this thing.

  [2014-07-07] Update: Added the option to cut the tips of the snaps which leads to trapezoids for high load couplings where minimal conversion of torosional force to axial force is important (suggested by @mechadense)
  [2014-06-27] Update: Odd values for Snaps are also allowed

• Use the customizer to make it fit or download it and adjust in OpenSCAD*
• To attach something to the discs you could either use hot glue or just add the discs to your design.
• As both discs of a disc-set look exactly the same you can also generate just one disc and print it twice.
• Using a high resolution could lead to long rendering times

  *) angleAdjustmentDisc.scad provides the modules

• singleDisc(Snaps, Diameter, SnapHeight, Resolution, ScrewHole, GroundPlateThickness, SnapFreeArea)
• discSet(Snaps, Diameter, SnapHeight, Resolution, ScrewHole, GroundPlateThickness, SnapFreeArea)
  that you can simply include in your OpenSCAD project.
