airbed fitting to schrader (update)

Made a model for F360

Taper starts at 17 mm OD and has a height of 15 mm with a 2 degree outward angle. 

Printed in PLA with 0,4 mm nozzle on 0,2 quality settings

If you attempt to replicate the thread in F360 

• Draw a 6,9 mm cilinder of your preferred mine is 10 mm
• use the “coil” option in F360. 
• Select rotations & pitch (see below) 
• depth of the thread is 0,4 mm [ = (7,7 - 6,9)/2 ]
• Join thread and cilinder.
• Schräder ID is 4,5 mm (no thread)

I added imperial for al non-metric users.

Metric: 7.7 mm OD, thread root diameter is 6.9 mm × 0.794 mm pitch.

Imperial: 0.305 in OD, thread root diameter 0.271 in × 32 tpi (threads per inch)
