Restoring original pizzacutter center caps

If they were my own wheels I would just try to eyeball the design from scratch.
Photogrammetry can work great for larger objects, but as you say there is lots of problems with it.
I havent used it myself because the better ones need a powerful nvidia graphics card and I have an ATi.
If you want I can ask around at work if someone has a 3d scanner in their box of toys?
They keep a few eggheads employed to try and maintain the idea that we are innovative (the eggheads are, the company in general...not so much).
They have 3d printers and I've seen 3d models from them that might have been scanned.
