Husky Rack Post Cap

I was getting sick of resting my hand on this sharp portion of the rack I have my printers on. Drafted up a quick sketch to put a protective cap on it. Much smoother and is a friction fit. Slides out with not much force as well. Fits my Husky branded rack. The specific rack I have is this one: https://www.homedepot.com/p/Husky-3-Shelf-Metal-Industrial-Duty-Freestanding-Garage-Storage-Shelving-Unit-in-Black-65-in-W-x-54-in-H-x-24-in-D-N2W652454W3B/319132819
