Custom camera quick release plate and l-bracket system

We need a unique quick release + camera L bracket system designed and modelled. We will supply initial sketches and rough models along with step-by-step feedback. The files need to be supplied as IGES files ready for CNC programming. What will make our system unique is the user removable pin registration dowels as per our current panoramic camera plates and files attached. All pin position data will be supplied. The system will be made up of the following: 1. Standard arca-swiss compatible quick release plate. 2. Pin registered camera mounting plate 3. Attachable accessories for L-bracket and cable holders.
