About this 3D model

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 FilesThe DWG contains my dimensioned reference designThe 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 scriptTweaking the scriptThere 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 surfacesdefinition = this defines the number of facets for curved surfaces (sets the $fn parameter)FeedbackThis is my first practical OpenSCAD design, so would welcome any feedback on how to refine either the object or my OpenSCAD coding style.UpdatesI've now merged this into a more comprehensive modular hose library - see http://www.thingiverse.com/thing:9457
