Making a 3D Pen Blank

[McGordon]

Are you using STL format to export to Cura?

If you’re using DAE that might explain the printing of a lid on the box.
Have a look at this thread:

Why are my designs sliced as solids in 3D printing slicers?

I have no idea what is going on with this, no idea what to look up to find answers, so I’m going to ask by myself. I am relatively new to 3D modelling, and made a mount for a motor using Sketchup.
