I'd rather keep the OEM design as well. I'm not too interested in trying to produce them myself but if we can get a good 3D scan of one that's brand new we'll have something to work from later. 3D printing is coming along in LEAPS AND BOUNDS. Who knows... maybe some day we will be able to 3D print them. I understand they would be "quite a test" of 3D printing tech at this point but maybe one day.
When that day comes.... We'll need a 3D model of it :). Failing the 3D printing maturing far enough... A 3D scan would allow us to approach someone with a better idea of exactly what we need.
