Upside Down Bottle Holder

I made this for my wife. She said when the dish washing liquid bottle gets low, the liquid takes a while to flow down to the nozzle; but this kind of bottle will not stand on its own upside down and she needed to find things to lean the bottle on.

I modeled the idea in clay to get the general dimensions. Then went to Fusion 360 to learn how to "loft". With a little experimenting on the internal wall thickness and bottle lid opening size, this is the result. {By the way, my wife calls it a "volcano". Ha!}

I didn't make it parametric, but if you know your way around in Fusion 360, you should be able to change the design to fit whatever size you need.

Simple default print settings are OK: 20% infill, 0.20mm, 2 perimeters, PLA, no support.
