One Inch Metal Shelf Caps

If you have any of those standard one-inch metal shelving units, and you decide you want to get two sets of shorter shelves, you can use these metal shelf caps to close off the top of the metal poles.  You can also use them on the bottom to prevent the metal connector from rubbing on the floor.  It's up to you.  Four of these took about 45 minutes to print on an X1C at standard settings for Bambu PLA with a 0.4mm nozzle.
