Intex outlet garden hose adapter

I've found the great Intex Pool Vacuum Adapter by mredmon and I was inspired so I changed a bit of his openscad file and printed it. But, hey, the thread was different (some mm bigger) than my Intex outlet thread! So I started a new model rewritten from scratch.
I've optimized several things of his already great design:

• Correct size and thread pitch (for my Intex pool, at least!)
• a better thread: the thread don't start and stop in a visible way inside the thread (as the ISOThread library is doing)
• I've used the ISOThreadUM2 by Trevor Moseley (thank you!) that resolve the problem that the thread is composed by many small bits. Using Cura to slice they where all small islands, very bad to print!
• I've made the hose adapter base smaller so that the cone has a constant wall thickness. Less filament to use and faster print.
• The knurled surface is complete (this is about taste, I liked more this way)

Please check your thread dimension if it's the same as the design as it seems that Intex has different sizes.

You can find the ready to slice STL or the original OpenScad file, if you want to tinker with it. In that case remember to download the two scad libraries in the same folder as they are needed to render.
