So I have used Stl and 3mf and every time I export and put it in my slicer it either Upscales it by 2x in 3mf or extremely downscales it in stl. Is this a known problem in shapr3d?

In addition to what slicer, are you setting the **units to millimeters** prior to exporting in STL or 3MF?

Set the units to millimeters and then export your STL again. It should work fine in whatever slicer you use.
