It's a mistake, anything else is wrong with my model? Is that the reason why my machine prints it in air?

Thanks :), it is a prototype model for glue dosing made in TinkerCad ;).

I dunno why you can not open the project, maybe because it was created on macOS, I'm sorry didn't tell you. That's the reason why I use Cura slicer- my machine is Ender 3 Pro and Creality's slicer is not available for me...

 

last screenshot bothers me... It looks different on my PC but I use almost full infill with 6 walls.

 

I remember i had similar issue with one model taken from thingiverse but I forgot which one... This one i have change a lil bit and now it seems to be ok.

Heres STL of my model.

 

 

[Ender 3 pro bad printing]

I had the same because of Bowden tube. It swelled due to high temperature.

It can also be:

- gap between nozzle and Bowden tube 

- too much retraction distance

- nozzle clogged

Optimization is great but i got small problem. One layer is printed in the air...
