This is a Roof rack inspired by the ARB Deluxe Defender/Discovery 1 & 2 Steel Roof Rack 1100 x 1350.
I used this to base the design upon. The roof rack measures 110 mm by 135 mm.
This is a working progress which I printed with a 25% infill and a course support material.
The mounts to fix the roof rack are designed to be a temporary measure and just "clip" onto the roof edging but feel free to develop something that is better =). Most items on the Roof Rack can be found on thingiverse thanks to over users publishing their work.
