Drain small swimming pool siphon attachment

I designed this model to drain my pool by gravity. My pool has a size of 300 cm * 200 cm *  75 cm. It will take some time, but just leave it be. You need a garden hose where the end of the hose will be lower than the bottom of the pool, otherwise gravity cannot help you.

Put the plate in the water and make sure you get the hose full of water before gravity will take over. I have a second hose connected to the tap to push fresh water in the hose and allowing it to fill up, once full, it will continue to flow.

You will need to add lead to the model while printing (or pause print). I bought some fishing weights of 35 mm by 10 mm weighing 20 gram each (see picture). Try to find the proper layer to pause the print where the nozzle will not touch the lead and will still fit in the model. I used a bit of force to get it in.

Also add a rubber to prevent any leakage. This model will fit any Gardena or other garden hose connector of 1/2" (13 mm).
