I plan to build a Kossel Mini as my first printer, but I don't like the limited build space. I am considering scaling it up, as I can get enough OpenBeam for a massive Kossel for only $12 more than the precut kit (I can cut it to size). I have a few questions, however.
Firstly, how is the build plate held in on a standard Kossel? It looks like it might be difficult to put into a scaled-up model.
Second, is it possible to use GT2 belts that aren't closed loops -- bind the ends somehow? If not, where can I get longer GT2 loops? Could I use fishing line instead?
Third, how rigid is the Kossel Mini? Could a significant scale-up cause too much wobble?
And fourth, is there anything else I missed? Any parts that would need to be changed for a scale-up?
