Parametric Modular Hose Segment

Inspired by http://www.thingiverse.com/thing:9006, this is an attempt to create a parametric loc-line compatible 1/4" hose segment using OpenSCAD.

For now I've only modeled a single segment, but plan to add accessories in the future (nozzles, mounting base, etc)

Description of Files
- The DWG contains my dimensioned reference design
- The DXF contains a cross-section ready for lathing
- "modular_hose_segment_from_dxf.scad" is a one-line OpenSCAD script to lathe the DXF into a solid (using rotate_extrude)
- "modular_hose_segment.scad" is the main parametric script
- "modular_hose_segment.stl" is a high-resolution STL export from the OpenSCAD script


Tweaking the script
There are loads of variables in the script to play with, hopefully they are all fairly self explanatory. I suspect the two most useful (in terms of tweaking the design for printing) will be:
- tolerance = controls the distance between the ball and socket surfaces
- definition = this defines the number
