Hi there,
This is Bogdan Andrei from Romania.
I'm a mechanical engineer, 3D modeler and industrial designer.
I have over 15 years of experience working in the mechanical field, and CAD/CAM.
I could design that rack for you as metal sheet so will be easy for you to send the files for manufacturing (laser/water cutting for prototyping or stamping press for mass production).
Based on your specs, drawings, sketches, I will make a primal model. On this model you may ask (if necessary) for modifications, adjustments, iterations, etc, until the desired outcome is reached.
When the final model is approved, I'll send you the files in order to get the rack prototyped/manufactured.
