M27 to M21 Socket Adapter

thingiverse

A socket adapter to be able to use a normal 21mm Socket on a 27mm oil filter "nut". Needed this for a 2010 Ford Focus 1.6 TDCI oil filter. Has a hole going sideways through the middle of it to be able to stick in a screw driver for torque if you don't want to use the upper socket, just remember it's still plastic, so if the oil filter is on too tight this might not work.
