It's a stand, for a cat bowl with a bit of an angle on it. It was designed for a specific 150mm cat bowl that's quite common. See pictures.
I designed it to be printed in vase mode, but the slicer couldn't deal with it, so I hollowed it out and it printed out fine.
Printed with an 0.4mm Nozzle out of PLA at 0.15mm layer height.
I made it a bucket so sand or something could weigh it down, but I haven't felt it neccessary so you could save yourself some filament by removing the bottom of the bucket.
