A blank order of the Arrow Lodge flap  for use as a base for any lodge flap.  its approximately the correct size and you can get 8 on a Prusa Mk4 build plate.  I use Sketchup to add features like a totem, the lodge name and event the flap is for.   in the photo, the top one is what i am giving you.  #BSA #OA #OAFlap
