TPU Flexi Fish Goby

I was looking for a file to calibrate my printer for TPU. 

But since I had problems with small overhangs, I used the fin from the original file as a tail fin, so I could also simulate small overhangs. Furthermore, I had problems with the retract values and wanted to try out what small areas look like, so the fins were changed.                                 It shouldn't be a problem to print the fish without infill.

In my case this was a great test object, have fun with your experiments.
