I've noticed in my Intex pool that the outlet is releasing the water straight out in the front and this lead to a non optimized water movement as on the outlet left a swirl is forming that is trapping some dirt and never releases, on the front an irregular movement is found and on the right the water is correctly going to the inlet (see the two water flux images).
This could be much optimized... so this modified outlet was born!
This outlet replaces the standard Intex one you've got with the pool. You'll be pleased with the result!
Please share your experience or if you have suggestions and don't forget to post a print of your new bended outlet at work!!! :)
Many thanks goes to Matthew Redmon that designed an outlet adapter that inspired me and gave me a start: https://www.thingiverse.com/thing:1649784
I've started modifying some of his openscad code but, after having print the first prototype, I've seen that the thread was not correct and the diameter was some millimeters too big, so the outlet had no chance to stay there.
I then decided to rewrite the whole thing from scratch. And that was nice even for exercice on openscad ;)
Pay attention to the threaded ring, I suggest to print it with something like -0.3mm XY size compensation to be sure that it will not have too much friction with the inner thread. Much depends on the precision of your printer... I've printed the inner part with -0.2 and the outer with -0.4 but you have to try with your printer.
I suggest to print the inner part and then print some trials with the threaded ring, as it's very fast to print.
That will make you know how much XY size compensation to use for the biggest part too.
I've used -0.3 with my New Matter MOD-t.
I've included the STL pre rendered objects ready to slice and the openscad file if you want to change something or use it as a base for something different. Use what you like most!
I've designed the base (biggest object) with openscad as there where no way to find the correct Intex outlet thread in Fusion 360 so I've used the (very good!) ISOThreadUM2 thread library by Trevor Moseley to create a customized one.
That was useful even for the knurled surface, very easy with another good library: knurledFinishLib by aubenc that you can find here: http://www.thingiverse.com/thing:9095
I'm actually loving the printed result!!!
The upper swirl and threaded ring where designed with Fusion 360, using one of the standard thread that was more close to the size I needed.
