This is the first functional thing I've modeled. It is a device you can twist on to a growler to let it dry after you rinse it out. The 3 "feet" print separately, just glue them in to the recessed 0.5" diameter circles on the bottom.
Printed and confirmed that it works. Fits snugly. Let me know how it works for you.
EDIT: Added a version for smaller print beds, to print within 127mm x 127mm.
