No worries about the vent, it's best to get the info out there. I also love the steel. It doesn't work for most of my designs, but when it does, it's fabulous and vintage-y. The zebrafish and my climate change pendant are two examples of pieces I like in steel more than any other material.
I don't understand why one of your bracelets would be polished and not the other. I've only seen the "failure to polish" like your feminist bracelet on smaller, more detailed pieces that I was sort of running as an experiment, but your pieces are close to the same size and level of detail as each other. Customer service is also a problem, and the delays are coming from ExOne, not Shapeways, because I always have excellent, within-24-hours service from Shapeways. And when you finally do get a response from ExOne, via Shapeways, it's usually not very satisfying. Hopefully they'll try again with the feminist bracelet, because it's a cool design!
Like I said above, I think the only way this is going to change is if a real competitor for ExOne opens up shop. Until then, there's really no incentive for them to pick up their quality control game or their customer service game.
