Stock tank hose holder

I've had a CountyLine stock tank as part of a custom water fountain for a couple of years now. A minor but real annoyance is in the need to secure the hose in some way while refilling. A good amount of the time, the hose would break loose and spray anybody unlucky enough to be nearby.

This hangs on the rolled-steel lip of any of a number of brands and styles of stock tanks (in Europe they're even remarketed as spas) and securely grips a hose to aim into the basin.

Designed with chamfers everywhere, so it prints without supports. DXF file included so you can adjust the parameters to fit your basin (they do vary in the width of the rolled lip) and hose diameters.

Also, note that my hose is one of the newer squishy ones; if you have a hard rubber one, you'll likely want to at least widen the opening on the model (which can be done directly in many slicers if you want to avoid editing the DXF).

UPDATE 3/6/2024: The PLA stretched for me, and stopped holding steady after a couple of months. I have added a new model that allows for a 10mm x 3mm bar magnet on both ends to secure it better and reduce stress (have secured it with superglue in the pic). I also recommend printing at 50% infill with a good pattern like gyroid to increase life.
