I am making a wall holder for my AC oil. For some reason when I bring it into my print program (Flashpoint) it doesn't see the inner cylinder/hollow.Blender Immage

  • $\begingroup$ Your model seems to have been made primarily relying on Boolean operations and reeks of bad topology. Boolean operations are bad modelling practice, lazy and well known for leading to a lot of problems including this. You model is full of NGons, use proper topology for modelling instead $\endgroup$ Jul 30 '17 at 3:25
  • $\begingroup$ This has pretty similar topology, should kickstart you in the right direction blender.stackexchange.com/questions/64121/… $\endgroup$ Jul 30 '17 at 3:27
  • $\begingroup$ Not sure how to make the holder hollow/ $\endgroup$

  • $\begingroup$ I expect the ngons are the issue. Try with this model. $\endgroup$

  • $\begingroup$ You're not saying how you export from blender: .stl? .obj? something else? $\endgroup$

I suspect your normals are inverted on the inner faces. In Edit mode, press A to select all, then Ctrl-N and re-export.
