Adapter to vent a pool cleaning tube using a water tap (Customizable)

SummaryBefore cleaning a pool you need to vent the cleaning tube to prevent air getting into the pump, which reduces the pumps power and even can break it.With a normal pool you simply dump the cleaner with the cleaning tube connected. Then you hold the other end of the tube against the pool inlet until all air got pushed out and the cleaner stops bubbling air out.However. For over 40 years this wasn't an option for me as the water inlet is around 1m under water and not reachable. So it was required to get onto my knees and shuffle water into the pipe until the tube was more or less air free. This wasn't very effective, took ages and I had to go to the maintenance room several times to vent the filter. So this took at least 20 minutes plus additional walks to get even started with the cleaning.Now I created this little tube adapter, which allows me to connect the pool tube to the water tap next to the pool. All it takes is to push the TPU part over the water tab, push the tube over at the other end, turn on the tab and wait for the bubbles to stop emerging from the cleaner head within the pool.This took less than two minutes without any pain, effort and walking. I never ever was able to start cleaning that quickly. I would have paid 30+ Euro for this solution. 3D printing rocks!As always I included the parts FreeCAD source file. It is nothing special and everyone can create this simple shape. Note:Yes, I know I could have just printed a straight and shorter pipe to result functional the same. I did this for three reasons. It would have take more material as it would have required to print the pool tube inner diameter all the way up the adapter instead of getting narrower towards the water outlet. Second reason is that the walls of the water tap side would be bigger and reduce the flex. Even less infill would probably have compensated this, but that would have affected the pool tube connection. The third an most important reason is that a longer peace avoids to get the entire adapter into the tube, which would be bad. I could have added a rim, but that would be over design and would have required support and/or resulting in less print quality. This way there is enough material to plug both sides in without risking to break or push it into the tube and it kind of looks cool.    Print SettingsPrinter: TronXY X5Rafts: NoSupports: NoResolution: 0.2Infill: 20%Filament brand: NoyesFilament color: WhiteFilament material: TPUNotes:I printed this part using TPU as it results in a more or less water prove fit, even so this is not required. I guess other materials would work, too, but TPU is the best for the job. Due to 20% infill the resulting object is relative stiff and even should fit on bigger or hex shaped outlets.
