RC4WD Blazer Hinged Tonneau Cover with Cab to bed wall set.

I personally don't care for a truck with a bed cap so designed a Tonneau cover for the RC4WD Blazer.
The kit includes:
Bed to cab wall.
Window Frame
Window cutout template
Tonneau cover and the arms.

Items needed for assembly
CA Glue to install the Bed to Cab wall.
8pcs 2mm x 10mm Self threading screws(or M2x10mm)
Make sure the arms are smooth on all flat surfaces.

Assembly
once your print is all cleaned up
Ream the holes in the Cover and Cab plate with a 1.5mm bit
Ream the holes in the arms with a 2mm bit
Fit the Cab/Bed plate into place to make sure it fits nice and snug
and then glue it in place so it is secure before continuing.
Attach the arms to the Cab/Bed plate as seen in the pictures.
Turn the body to one side and attach the arms to the Cover as in pictures.
Turn the body over carefully and attach the other sides arms to the cover.

That should be it.
