Maybe a tour of the 'underbelly' of the printer for the technically inclined. What the boards are, that sort of thing.
Umm yeah - you know, I never did turn her upside down - well it's not polite to look up a woman's skirt :-)

So yep would be interesting to see what's down there :-)

Oh and maybe some thing on whether it's possible/easy to move the creator's on/off button from the back to the front. That's really my only issue on the whole design.
I'm guessing it's physically attached to the psu - but could it be moved by someone who doesn't solder ? (ie: me)

I've had the extruder to bits - that's pretty straightforward.
Maybe a video on how to get ninjaflex working. IE: which parts I need to print and how they fit within the existing layout.
