So you have played with kbricks enough to know that you want to build something big, but for that you're going to need more connectors, pegs and axle rings. A lot more.
This uses the original design for connectors and pegs, but allows you to print a grid of them in one go. Choose Print long connectors; Print short connectors; or Print pegs, and how many you want (width x depth).
If you set Print Supports to yes, then it prints thin connecting pieces at the bottom. I found that I had good enough build plate adhesion that this worked well. Once finish, just cut the parts out with a pair of scissors, and maybe finish up with some sandpaper if needed.
If you prefer to print with a brim, then set Print Supports to false, and just add a brim with your slicer.
Note that depending on how your slicer and printer work, you may find that printing parts this way works LESS well than just printing one at a time. This is because the printer will retract filament between parts. I found that it worked really well for the connectors, but not as well for the pegs.
Do let me know in the comments if you have any suggestions or tips.
