This is a Camera mount for the Logitech C170 that fits between the black rigging and actual bed of the MP Select Mini.
The c170_underbed and extension both are printed and glued together then the camera can easily slide into the Mount while being far enough away to see on Octo Print or Astro Print
IF you are using a glass bed Check out this remix http://www.thingiverse.com/thing:1952480
He did a great job of making it so this would fit on the glass bed.
support is only needed for the c170_underbed.stl
