I had a couple prototype parts made with a Makerbot recently, they turned out... OK.
Had a stereolithography print made and picked it up today. Pretty impressed what the
Formlabs laser-gel printer can do. MUCH higher resolution.
This might just be a serviceable part, until we can go for plastic-injection. I wish I could have seen it before he did some finish-sanding on it...
By comparison, here's the first Makerbot print.
