I wish there was a star-based rating system, but I hate leaving "negative" reviews. Regardless, the purchase downloaded and unzipped fine. File structure and folder organization were excellent. But the STL files wouldn't open to the correct scale in Cura. Additionally, half of the files were corrupt or required repair before slicing. Once repaired, they weren't oriented correctly for bed adhesion and support. I abandoned the print an hour in......didn't feel like devoting a week to file prep and repair. IMO, a purchased print should be ready....right out of the box, so to speak. I do NOT recommend.
