Would it be possible to increase the build size of this kit? Not worried about projector resolution or focusing from a further distance.

Considering I'd probably only use very few pieces of the framing kit since I want to go a bit bigger, should I just piece out some of the smaller bits? Coming from a kossel printer I built from open source guides, I know a bunch about firmwares and boards, driver motors, etc for FDM printing. But I know nearly nothing for SLA mechanical parts, boards, and so on.

Is there a good source for open source SLA builds like the google deltabots group?
