Beer Tap Spanner

thingiverse

The spanner was created to tighten or loosen a 32mm diameter retaining ring on a beer tap. I used an M4 x 6mm screw for the spanner tooth that fits in the beer taps retaining ring. Although the hole that takes the screw has a thread I suggest that you run an M4 tap down it to recut the threads to make an easy fit when inserting the screw.
