Rocktopus for TPU v1.0 (STL problems)

This is a blend of two models:  Dwayne the Rock Johnson's head and an Octopus.  I made it with the intent to print out of TPU.

I used Blender to chop and combine the two models (badly, I might add … in that it is not a "clean" STL file and there are a few things I want to change).  I'm sort of new to Blender so keep that in mind.  My cura threw up model errors, but it still sliced and I could print.

I'm calling this v1.0 because I “intend” to clean up the model … cough, cough … 

There are other versions of the Rocktopus out there, but they are articulated - I wanted one I could toss around and not worry about something cracking or breaking.

I printed on an Anycubic Vyper.  Here were my settings:

• Layer height = 0.2 mm
  • Initial layer height = 0.3 mm
• Hot end = 220 C
• Print bed = 50 C
• Infill Density = 20%
• Flow = 105%
• Speed = 40 mm/s
• Retraction = 7 mm @ 50 mm/s
• Fan speed = 100% with initial layer at Zero
• Printed with a skirt

This was printed from a spool of Overture TPU which I had just recently dried.  I didn't have a fancy dryer - I just placed the spool in an electric oven set to “Warm” (so less than 200-deg F) for about and hour and a half, then I turned off the heat and let it cool back down before printing (about another hour).  Seemed to work out OK - good enough for my purposes.
