Tap tower wrench
thingiverse
1 1/16" (appx 27mm) beer tap nut wrench. Preferably print at least two of these and stack them facing in alternate directions around the nut. This will work to tighten a hard-to-reach tap handle nut better than finger tight, but you really need something made of metal to tighten more.
