Remixed from mike_new model. Identical except I've sealed the drainage hole so this can also serve as a container or cup or anything you want and should be watertight depending on your print settings/material.
I've printed it at 70% scale at 0.15 mm layer height. Took 6 hours to print on my Original Prusa i3 Mk2.
According to Simplify 3D, at 100%, this would take around 12 hours to print with 130g/44m of PLA.
No support, raft or infill needed.
