Cricut Maker Roller fix

The Cricut Maker has had a problem ( on some units ) where the roller on the paper hold down bar will migrate off the edge of the cutting mat.  This will cause the cut to fail.  The details are in the reddit link below.  The net of it is that a McMaster - Carr clip was identified as a fix / workaround.  While the metal clip is a good solution, I used the McMaster-Carr design file and made it an stl.  You can use this to get back in operation while you order a part.

Not much done here except to make the stl available for someone with this issue to get back cutting.
