First thing i did was to insert blueprint canvas in my design software Fusion 360

Ive inserted a right, top back and frame images.

Here's the right view.

From that view I designed the frame and extrude it. You only see half of the frame as I plan to use the mirror command to generate the other half

I plan to validate early on that the design is sound.

Here is the first print out of the frame so far

Some assembly is required since the frame is too long to be printed on my printer's bed
