We are the Zappos/Newegg of 3D Printing

Zappos and Newegg are not similar enough for them to be slapped together like that, unless you just mean "successful specialty retailer"...

Otherwise, what makes you like them? Zappos has a bold, trusting, happiness-oriented company culture. Other than that, they're just a retailer. Is your culture like theirs?

Newegg became successful due to expert product reviews, great customer service, and a wide range of inexpensive products. Is that what you're emulating?
