I build most of my benchtop tool stands and was searching for a source of sturdy adjustable feet. It occurred to me that hockey pucks would be an inexpensive way to make them myself. The rubber is very tough, and it band saws easily. I cut two 1-1⁄2″-diameter feet from each puck and drill a bolt hole about three-quarters of the way through them. Then, I install a length of threaded rod in the hole with epoxy. Add a washer and nut to complete a pair of very rugged feet.
