A simple "inbox" or "paper organizer" type thing for papers, magazines, etc. Designed to save space on your desk vs. lay-flat organizers, plus, it prints 100% with NO SUPPORTS!

This one is A4 sized, but you can scale it down for other paper sizes, or to the max of your printer bed, and the ends of your paper will just stick out. No sweat.

You'll need to have your retraction settings dialed in very well, but it will print with no supports, no skirts, no rafts, no brims... It just takes a long time!

I suggest PLA at 190 degrees if possible, as other materials will string quite a bit
