I'm on a roll with making back quivers thanks to Bud B.'s tutorial, Soap Creek's thread on his quiver making addiction, and additional encouragement from Dorado. Thanks, guys!
I've made two different configurations:
The one on the left was my first project, and I based it on the quiver I bought from HHA a year ago and is 22" deep, and the one on the right was done using Bud B.'s "recipe", and is 21" deep.
The HHA version is quite a bit larger in all the dimensions:
I'm thinking that the larger bottom of the HHA quiver allows the arrow points to move further to the back edge of the bottom when the quiver is broken in and forms to your back, allowing the nocks to tip forward, putting them closer to your shoulder for easier removal.
I am use to having my arrows off to the side a bit more like Howard Hll and John Schulz, so my clone is more appealing to me at this time. I haven't tried the new one yet, so I may change my mind on the subject.
I don't have any reason to make any more right now, but Christmas is only 11 months away......
