Simple parametric Y-connector

A Y-connector for attaching flexible hoses. It's customizable but there's no error-checking so if the various shapes get weird at extreme sizes maybe don't do that?

The barbs and stops can be removed. Instructions are in the [Customizer](/apps/customizer/run?thing_id=6891135). (Since Thingiverse Customizer is somewhat broken, I recommend the excellent [OpenSCAD Playground](https://ochafik.com/openscad2/#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
