Bob,
I have been using? your fixed fixed design since I received the sBitx, it has worked well!??
My design uses the sBitx as a cantilever with the rubber feet going into the base to provide the support end.? So stability is provided by the length of the 3d printed feet and doesn't need a back brace.? I went through a couple of iterations of "too short...too long" before I settled on the current size which is pretty stable.??
