Just received the rev 3 in red. Fit is 99% perfect. There is 1% room for improvement in the way the part sits on the sides of the fob. Seems to be 0,5 mm off centered to the bottom wrt the chromed decor. I have tried both parts received on the two fobs that came with the car. Same issue.
The material is as smooth as it come be given the process. It may attract or grab pocket furr with time. It is most ideal for painting or vynil.
Shapeways shipment and transit was great. This was my first order with them.
