Makerbot Digitizer Calibration Tool / Scan Backdrop

Gently place the grommet back on the laser. Check out the scanning backdrop as well. Hopefully it will help with the stray light and block movement in the room. It worked surprisingly well for me. Scanning Backdrop - This works really well for a clean scan. It must be flat black. I am sure it can be painted if needed.
