Adjustable PVC Joint

This is a work-in-progress.  There are several improvements to come, but I think it's complete enough to be useful at this point.

These two parts can be used to join 1" PVC pipe at several angles and can be adjusted by loosening and tightening the 1/8" bolt that holds the joint together.  Theoretically a spring could be added to the bolt to allow the joint to be adjusted without tools, but this hasn't been tested yet.

I'm working on making the design function properly as a parametric model so that different pipe sizes can be used, but there's some kinks to work out yet.  I'm also experimenting to determine the strength limits which may result in some changes to the teeth, etc.
