This is a stand for drying out 5-gallon water bottles upside down. I originally made this in FreeCad but moved it over to OpenSCAD so it would be easier to customize. The default values are for the stand I printed and work for jugs with a standard 55mm diameter top. To make sure it's advised to select a Neck Size and the Test view and then print the test piece to double-check.
