Maybe you get some comfort or at least not be mad at the printer, by knowing 1 printer to print an entire suit with enough time to finish it and all the other build out... In less than 30 days... probably wouldn't have made it anyway. Not unless you take the entire month as vacation, do nothing else and only live to process the costume as fast as it comes off the printer, in real time. And even then... ehhh... I have my doubts that one Anycubic Max will crank enough parts out fast enough because it basically means printing an entire suit in 2-3 weeks to leave time for seaming, sanding, painting and everything else.
You might have better luck asking someone that has a suit (which will be scaled and tailored to their build not yours), if they would come and appear at your event. Folks that own armor cosplay are generally always looking for any excuse to wear it out, make an appearance or promote the hobby and the group.
I know I personally wouldn't want someone else sweating in my under-armor, or risking their inexperience at being in cosplay armor to cause them to fall, hurt themselves, someone else, or break elements of the suit.
