Hello -
Ok, the plumbing washer you see below has been a PITA because the glue I use to hold it in place doesn't adhere :
It has been replaced by a modified furniture foot :
1 - The furniture foot
2 - Cut off the bottom and drill a hole in the top-center
3 - The faux plastic lug nut (this one is unmodified, no hole drilled in center)
4 - The furniture foot pressed onto the lug nut
I also sanded off the bottom of the furniture foot, the "donut-shaped" raised part. This made it pretty much match the height of the plumbing washer.
