Hose adapters for all common (at least what I could find online) hose sizes.

All adapters have:

• Each size has an option of Outer Diameter measurement or Inner Diameter. 
  • Outer Diameter (OD): Intended for the printed tube to go inside your existing hose.
  • Inner Diameter (ID): Intended for the printed tube to go over your existing hose or nozzle.
• 40mm long connector at each end
• 3mm taper on each connector, from -1.5 to +1.5
• Wall thickness of 2mm
• A hose stop on the large end

These were all generated with this OpenSCAD Parametric model. If any of these don't suit you can customise your own, or let me know and I can generate it.

• Added sizes, 4.5", 5", 120mm, 125mm, 150mm

• Added Internal Diameter (ID) connections. Previously I only supported Outer Diameter (OD) only. Now there is ID-ID, ID-OD, OD-OD. 
• Removed redundant sizes where the Metric and Imperial sizes are very close. I.E. 1.25in is 31.75mm, so 32mm is not needed.
• Included connectors for connections two of the same size hose together.
