Very difficult puzzles

I have seen many different puzzles on this platform. I myself am a big puzzle fan, but to this day I didn't find a puzzle that made me insane enough to jump out the window(in Minecraft). So I sat down to fix this problem. The model itself is a really simpel design I put together in around 60 min. It consists of 20 puzzle pieces and one frame piece. The objective is to put all the pieces in the frame. The difficulty is that there is only one solution. I made sure that there would be only one, by making 3 redesigns and many, MANY, hours of puzzling. I have not found a second solution, but if you do i will change the design again and give you a packet of nothing wrapped in invisible nothing paper decorated with nothing at all. So, for print settings, I would recommend you to use a standard 0.20mm layer height settings. Also, merge all the pieces together, so you know where every piece belongs. The tolerances between the pieces should be enough to not fuse together as one. Maybe put so
