Uploaded to Prusa slicer from Fusion 360 and the scale was way to large. This is fixed as I tested it after saving and printing to verify.
Here are the scale factors, X10, Y10, Z10, and size world is X83.5mm, Y 125.5mm/ Z17.69mm.
Printed on a Prusa Core One. PETG.
The author remixed this model.
Added two finger clearance areas to make it easier to grab cutter out of tray.
