Tevo Tarantula end stop Y/Z bracket

I loaded up the original .stl in Cura and Craftware they seemed to show that it would print solid.

I installed MatterControl and loaded it up and it looked like it would print with holes. I don't like to connect my PC to the printer for prints though so I exported the .gcode and printed it that way.

It printed with holes but didn't print the top layer so it was a bust.
I tried printing from Cura anyhow and it printed a solid slab as expected.

I imported the .stl file into tinkercad.com
