Openware E2-200 3D Printer

This is my first 3D printer design/build. It has a 200 x 200 x 200 mm build space. The construction is 2020 aluminum extrusion, laser cut acrylic, and 3D printed ABS. The twin extruders are individually adjustable from a thumb screw above each mount. The extruder design is based on the Wade Extruder but was modified to work as a dual extruder with more adjustment capability. Over all it prints well and is very reliable. I am currently working on second rendition with a large build space and a redesign of some components to increase printing speed and overall system simplicity.
