Alex is the man, seriously. he helped contacted me before printing my project so i don't waste my money, on checking on sizes. which was good, because all of them were off. saved me a bunch of money and headache, not only just that he walked me through everything on scaling and adjusting my prints. you couldn't get better customer service and satisfaction than him. i been to two other shops before him, and none of them were as enthusiastic as this guy, Alex.
Not only just that his prices are great for his quality, his quality ranges, you might think his high quality might be overprices but i got pieces that are as small as 11mm big and they look exactly like my cad files, i couldn't get that quality unless outsourced, he is local bay area and i believe he offers to deliver within SF (pretty much same day printing if he isnt busy).
The guy helped me out til 1 am just walking me through things, if that doesn't say dedication. you guys may be asking for too much.
HIGHLY RECOMMEND, couldn't find a better guy to help you with your 3d projects or your 3d printing needs.
