The very first thing I had to come up with is the stand for the instrument. I opted for the aluminum tripod stand for the lighting equipment (I believe that's what it was). I bought two guitar neck supports which are made from thick steel rod with a foam sleeve over it. The supports were easy to bend and reshape. I used one support the neck of Stagg, and the other to rest the instrument on. I re-drilled the pivot point of one of the legs of the tripod such that in the collapsed state all legs are still in parallel to the body like for stock tripod, but when all 3 legs are spread apart, the stand tilts toward shortest leg and stands at the angle. As a result, the instrument leans back, which prevents whole contraption from tipping over. The bottom support is removable. I've made the gap between rods just large enough for the end pin to fit in there. The instrument rests on the collar that holds the end pin.
See the photos below.
Collapsed stand is abouth the same size as the Stagg in the carrying bag.

Bottom support removed for ease of transporting - no sticking out parts.
Top neck support. It can be removed, but it is so unintrusive, I've decided
to leave it on permanently.
