I had a Berkely Wall Fishing Pole holder that holds 6 poles and ran out of wall space in the garage so moved it to the ceiling. It was a bit of a tight fit for 6 poles and getting poles in and out just didn't work very well on the ceiling (frequently dropped a few). I found the design by Auxon and remix that fit my print bed but when I printed it, it is quite large and used a lot of plastic. In addition, it took up too much space on my ceiling. I shrunk the design down, moved and resized the screw holes, and they are perfect. It holds 6 poles now in a 1-foot wide section of ceiling.
