Do you have a projected date in mind yet for when these might be in the store? I bought an Apache yesterday and looking to do the same as you - row of flat bottomed ones on the bottom, stacking ones up top. I've got 8Vs too, and as you know, there's really nothing out there to buy off the shelf...I've been printing racks for my 1200 chip 8V limit set and refining the rack design as I go. The bottom rack is flat on the bottom. I'll have a layer of those on the bottom of an Apache case, then 6 regular racks stacked on top. I'll be sharing the model soon, and I'll put the 71mm racks for the 8V China Clays in my store first. Then I'll move on to racks of other sizes.
These things stack like bricks!
