Cross Style Insert for 180x110x50mm Ultimate Parametric Rugged Box

I could not find a premade insert anywhere so I thought I would post mine to save you time if you don't know how to make your own insert. I made the insert from the original model's default fill. Printed at .2 layer height at 15% infill. Also, I uploaded it with the print orientation upside down, so flip it So the curved part is on top when printing.
