Designed to hold 4 cues (of reasonably similar length :) ). Each half of the mount attaches with two #6 fasteners (holes are pretty generously toleranced, so should be easily cleaned out up to a #8... I think). I have printed both sides in both resin and filament and both turned out just dandy. Because I did not alter any of the surfaces produced by the GD solver, the upper, in particular, is a bit unfortunate from a support material need perspective. But, I was able to print and clean up two of them without too much hassle. I really like the way these organic structures look in resin, so that's what I ultimately went with on my wall :) **"Lessons learned"** One significant(ish) revision I think I'll probably have to make in the future is to modify the Upper to have larger openings...shouldn't need to be a sharp shooter to put the cue AWAY I suppose. It works fine as is, and I'm planning to use mine until it won't let me anymore, but I can see one....libated?...guest missing with confidence and breaking it. Also, while I love the look of the 'tendon' connections between the two sides of the upper, I'll also likely stiffen that. On the Lower, I love it actually. I am extremely happy with how it came out and hope to not take it down till the next move! I've included the two GD setup files, in case anyone is interested in takin a look. I also have some notes and such from when I was creating the models that I'll post a link to later if there's interest!
