Needed a hose adapter for a project. Loved the OpenSCAD parametric approach created by SsteveSstrong, but wanted to add a slight taper option to the source and output connections. I modified his original code to add the sourceTaper and outputTaper parameters. Many thanks and kudos to SsteveSstrong for his beautifully elegant and easily modified design.
