Simple perforated cylindrical stand that allows a carboy to be set on it inverted, without the top of the carboy touching the floor/sink. The perforations are intended to allow drying. It is intended to be printed upside down, that way there are no overhangs greater than 45°. I used ABS, with a 20% infill, and it seems sturdier than necessary. Here's a timelapse video of the printing: https://youtu.be/p-Xx8uj7Xjc
