Ordered a tool for my uKeg but as with most things GrowlerWerks you're probably better off doing it yourself.. Printed parts worked well enough for me when i applied pressure across the mouth to ensure the tool engages properly .. models provided without any guarantee of usability.. (i.e. don't sue me if your house burns down due to incorrect fit or poor instructions).

Modeled after pictures of the actual tool, might consider making the groove/ridge ratio 30/30 instead of 25/35 as it seems the official tool is.
