I've made all the ones that I could ever need, in versions that work with cases and with overhanging viewfinders, but I don't want the bother of qualifying Shapeways as a supplier. I think that their product would be very good but the price would be high and combined with what I suspect would be a small share of a small market I don't think I would make much money at it. I could one day run some off in reinforced nylon and sell them directly via eBay, but my entrepreneurial urge is not very high.
