SummaryI printed this in my Filament Friday #40 and Tuesday Tech Tip #3 episodes on YouTube. This file was run through netfabb to clear out any errors. My older version of Simplify 3D left holes at the bottom of the spiral. I then printed it with the updated v3.x and it printed great. I also tested Cura and Slicer in the videos. https://youtu.be/G4WGrKvCOUg and https://youtu.be/nNM34ldvZ-0
