Printing supports experience was really tedious, so here I added to my previous version https://www.thingiverse.com/thing:3089517 three more legs designs to minimize the need in supports. (I am going to add one more in some future). Despite that I liked previous tripod appearance aesthetically better, this approach has its own technical drawbacks, in particular, finishing threads is really tricky. Nevertheless, now there is a choice.
The toppings are in fact taken unchanged from the previous version (and interchangeable).
To make the first legs design you need three 'legs1' parts (may require some support in printing) or three pairs of 'legs1in' and 'legs1out' parts (I printed them without any support) and three nuts.
To make the second legs design you need three pairs of 'legs2in' and 'legs2out' parts, one 'node' part and six nuts.
To make the third legs design you need three legs3 pairs and three nuts (legs3s file contains additional manually encoded support which was helpful in my case). The final assembly is somewhat tricky (and seems to be impossible with a rigid material and smaller tolerance values so this design is probably should be revised). If you are going to glue parts than think about proper assembly order.
'nuts' files contain the nuts design in 'ideal' sizes while 'xnuts' has small extra addition to the thread diameter to compensate thermal shrinkage and to simplify the thread finishing.
(This extra depends on material, printer, print settings etc. in the general case.)
I used metric M10 thread-cutting tools to finish threads.
It may be good idea to glue some parts together (though I assembled everything without it).
