This is a factory 914-6 clam cover. A real one on my 6. Please note the factory texture on the part. If these are done as a 3/d printed part, to get it to look somewhat ok, a person could sand the shit of it and go through the grits and spray with a paint with a satin finish or go with some Novus 2 or 3 by hand till you get the finish you want? Parts made from an original primo one in a mold and cast in bk urethane may come out ok if the people doing it knew there stuff. That is why there are non for sale currently by secondary sources. I think that 914 Rubber has the skill to do this.
Now they could be 3d printed and then run through a large vibratory finisher with the right media and then come out as a satin finish, but this takes days and cost a bit of money. I am not in this biz as a job shop, but do have the equipment to do this kind of work but I do it with Lucite blocks as art that I sell at art shows.
Good luck people,
