Had my first 3D print fail today. Grabbed a file off Printables, brought it into the Bambu Studio and accepted the values and just printed a car phone mount that was about 200% too big, like comically, hilariously larger than any phone and the mounting points were also double sized so it wouldn't even work with a tablet.

Now I get why people have calipers on their desk to measure everything precisely in millimeters before hitting the print button.
