Era is a fast, cheap, simple, robust 3d printer design.

This project is greatly inspired by [Ultimaker 2 Aluminum Extrusion 3D printer](http://www.thingiverse.com/thing:811271).

## The Era Principle

Era is designed with the principle: minimal efforts to achieve professional grade.：

First, it is designed to be easily printable from any present printer. As most printers print in PLA or ABS, which are not as strong as metal or polycarbonate (the most common casing and part material on mid-to-hign end commercial printers), Era parts are designed to be very thick and stiff. They may not look fancy, but have a unified clean look, easy to print with minimal support, and is strong enough (sometimes over-strong that you may think it is wasting material, but the structural strength will pay in time) ,making it viberation-resilent and durable. Calibrate once and run everywhere!

The second is the massive use of standard metal parts. Standard metals parts are stronger than p
