Anyone have a threads.xml file for garden hose thread?

[bentwookie]

Fusion 360 doesn't come with built-in support for garden hose thread. Per this post you can edit your own threads. Has anyone done so that would mind sharing their xml file?

It goes without saying, that a thread editor, or built-in support for garden hose threads would be appreciated. (and the tops of 2-liter bottles, whatever they are 🙂 )

Thanks! I'll give it a shot. 

I really do wish they'd spend some more time on supporting custom threads. It's so much easier than all this.

You are right, but it's just a matter of time before they will add it 🙂

I found some specs in this forum (http://www.practicalmachinist.com/vb/general/garden-hose-thread-specifications-question-289763/) and created the file "GHT.xml" with the following content.  I've tried the external thread, but not the internal.  Your mileage may vary.

Thanks for putting this together! I finished the last project using the coil tool, but have another project coming up that will need hose thread again. I'll be sure to try it out!

I have printed both the interior and exterior with PETG on a Prusa i3.  I found the NH to be too tight and had to alter the scale my prints by 2% to get a comfortable fit.  The NHR variant would probably have worked better for my application.

Also, the <TapDrill> number is fiction.  I didn't know whether it was required, so I just put in a swag number.

I found the best option is to use the coil function.

For internal thread, draw a tube with internal diameter of 24 mm. draw a coil same diamter, triangle (external) shape, Section position - Outside, pitch 2.21 (+ or - depending the direction), Section Size 2.25, Operation Cut.

For external thread. draw a tube external diameter 22 mm, Coil 22 mm, pitch 2.21 (+ or - depending the direction), Setion - Tirangular (external), Section position - Outside, Section size 2.25, Operation Join.

Dimensions may vary slightly depending on the filament type and how tight you want to fit it. Make sure the coil do not start or end at the end of the tube to make sure the sealing face is flat, otherwise wont seal the water properlly.

Hope it helps.

Thank you for posting the .xml for 3/4" GHT.  Do you have an .xml for 1" GHT also?
