Overhang and recovery challenge

This print is designed to be impossible without supports. The printer will fail, that is not a question. But this test also serves to help you see how fast your printer can recover. By recovery, I mean, the ability of the printer to place enough messed up filament that it recovers on a higher level. This can be especially helpful if you, like me, sometimes use Meshmixer for support structures and when printing the support structure fails at some point. It also serves to make some interesting art should it fail and create some droopy circles.

Also, if you are really feeling interesting, there is now a second version with an additional double arch on top that has a radius of 4.5 cm. Should also prove difficult to print. Another test for your printer!
