Found a new product and figured I would share. Makerpipe.com sells end caps $5/10 and heat shrink tubing $8/10ft for 3/4 electrical conduit designed for desks. Nice aesthetic touch for anyone interested and seems pretty durable. Couple tips, first blow into the collapsed heat shrink to decompress it. A lot easier to put on. Second, wipe the conduit down with rubbing alcohol to remove dust and contaminates. Beyond that, slide it onto the conduit and use a heat gun to apply.
