It was too much work. That's the short of it.
Design was significantly harder because you had to factor in how drafting would work with various combinations - so it was like designing 10 cubes that all went together. I also disliked being forced into a color, which was very obvious when you were only drafting 2 modules (but even with 3).
It was a fun experiment though and this is probably the cleanest midrange cube I was ever able to construct all things considered. There are certainly better cubes out there though.
