Filament reel holder

I wanted to store loose filament out of the way so I made some small brackets that mount to the wall with keyholes and screws. It uses ½ inch PVC pipe in a 2 foot length purchased from Home Depot. You can use longer pipes but you may want to add a 3rd or 4th bracket to reduce sag. The keyholes are 12mm wide and 4mm deep. The picture doesn't show it fully loaded but I've had 8 brand new reels on it with little issue.
