Cusomizable Parametric Organ Pipe

One of the hardest parts of designing the pipe organs (http://www.thingiverse.com/thing:1037991 & http://www.thingiverse.com/thing:1051888) was getting the pipes to work.

I found the equations on http://www.rwgiangiulio.com/ extremely helpful but this still required modelling each pipe individually.

I have now come up with this parametric version to make it simple to make different sized pipes by just entering the variables.

Hope you enjoy!
