This is a great example of reserve engineered CAD work to create 3D printable files. In this case, the customer was repairing a ping pong table where the parts were no longer able to be purchased. The parts were designed and printed and worked exactly as necessary for the application. It is worth noting parts that don't need critical feature like the red bracket were simplified for 3D printing, but it was modeled both way in case certain features were necessary. These pieces were printed in PETG, black and white respectively.
