Ethernet Cable Corner Cover

Was looking for something to cover an ethernet cable that runs up a wall in a corner and couldn't find anything. This is meant to be painted and match the color of the wall in an attempt to make the cable run blend in to the wall. This is not meant to be structural; it does not hold the cable tightly. Any double-sided adhesive should work to secure it to the wall. I personally use Gorilla Mounting Putty.
