Why won't Taz5 print this damn crab mouth!

Ok so in 123Design there is a mouth which I created. In Cura the crab has a mouth laying on the simulated bed. My final outputs have no mouth. Driving me nuts!

Anyone of you guys use 123Design and Cura?

Thanks.


The thickness may be too small, try making it a bit thicker

Sounds like a plan.

More than likely it’s not a water tight object so it ignores the mouth. Post the stl so we can have a look

The smile looks very thin. Cura is probably not printing it. Make the smile thicker, and it’ll print.
