I have so many questions.....Would parts from different kossels work on your printer, for instance the extruder mount? Is there any chance you could change its to LMU8 instead of LM10s? Do you have any plans to release the design files? Have you considered using NEMA17s instead of NEMA23s? Is there a specific reason you picked these motors?
This seems like the simplest delta 3d printer and also the most recent attempt I've seen but I hope you don't mind if I try to modify to fit some of the parts I already have on hand.
