Car defroster w/ replaceable blades & storage

This is a car defrosting with a hexagonal pattern. The model file comes with the scraper, 3 blades with notches, and a storage area for extra blades. If you print this, please let me know what your settings were and how well the model worked for you. Thanks! Also, it would be a great help if you could share this with your friends and anyone you know who has a 3D printer.
