Back Drop for FABSCAN by Ceb

I think part of the problem with the scanning not getting a cloud result is the missing backdrop. Fabscan seems to require a backdrop in order to stop the lasers and create the solid line behind the object being scanned.
I will upload the images after I make this object. It requires 3mm screws to connect it all together. 20mm length screws are required for the connecting the assembled Backdrop to the Backdrop Sled.
The rest of the Backdrop should be able to be assembled with 12mm length screws.
I have included how to connect the backdrop as one piece.
I have uploaded the new connectors as the first ones did not fit. I was off a mm for the small and way off for the long one. Remember to put the pieces together, you will flip one of the top, one of the bottom and one of the long connectors during assembly.
