For those of you who want to scratch-build the extended basket instead of buying my $22 3D print, here are the dimensions of the design to help your endeavors:
Width 73.8 mm (from top to bottom in the below photo) × Length 51.3 mm (from the left side attaching bar to the end of the edge of the basket mesh) × Height 12.9 mm (top to bottom of the basket itself)
Use the photo below for attaching or as a template.
You can also see other reference photos on my post:
I hope this helps. 
Kind regards,
James
