Hi, I'm trying to make a cylindrical frame out of quarter sectioned rings and supports. The files are attached below so that you can see what I'm trying to do. The supports fit into the ring perfectly as far as I can tell but then when I place a ring on top of those supports (so that from bottom to top it goes ring, support, ring) the upper support doesn't line up with the holes for some reason. I've tried redesigning the ring and checked all the measurements on the support but it still doesn't work. Could you take a look at it and see if you can find the problem?
The files attached are the quarter of the ring, a support, the ring fully assembled, and then 2 files of the full ring with the supports attached to it. Try stacking sub-assembly 1 on top of sub assembly and then look from above and to the sides and you'll see what I'm talking about.
