Tennis Ball Sound Insulator for Sim Racing

Sound deadening feet for your sim rig. Quit annoying your neighbors today! Made it as a temp fix while I saved up for those springs, ended up liking it way better than expected.  Also slides across carpet/wood flooring without scratching. Makes it easy to put away when I have people over.  Just use whatever bolt works for your application. There's a hole for it. In my case I used T slot nuts, but wood screws could also work on wooden rigs. Also note how my bolt head protrudes significantly - this has caused me no issue. I also ended up using 12 tennis balls, this is probably overkill. I also noticed moving more towards the back rather than spreading out evenly seems to hold better.
