Corny Beer Drip Tray

The goal was to design a small drip tray to standard cornelius kegs, that can be floor mounted or raised and somehow attached to the keg. This is achieved in current design with a belt.

I printed the tray in standard PLA, and the Hopsgrid in flexible TPU for better grip.
two O-Ring slots foreseen to avoid PLA slipping over keg surface. Initial design had an error on keg diameter, and O-Rings where replaced by a wedge. This is shown on the picture. Uploaded design was modified to correct it, but not yet printed.

The Hopgrid is a remix from https://www.thingiverse.com/thing:1286779 (Trying to link this thing but somehing happens, I'l try to solve it)
