That sounds fine I think a lot of people would go for that..Nice one. I have the idea of 3d print this cap. I did the model in 3d including letters. Maybe Ill try one in black Abs to see how it looks and I order a 10-20 units batch. Which price would you think is fair? 6-8€+shipping? Maybe I can send a batch to Uk to avoid shipping costs snd customs?
