LulzBot Greban Knife Cover
thingiverse
The Greban knife included with all LulzBot brand printers is a good tool to use with the printer. However, as the blade is not entirely dull, it can still be somewhat of a safety hazard. On one side of the cover it says "CAUTION", and on the other it says "SHARP". The arrows on both sides indicate which way the blade should be inserted.
