The RepRap Lewis is named for Edward B. Lewis, an American Geneticist. The primary design goals are accessible documentation and high replication ability. All working documentation and recommendations are stored on the RepRap wiki.
This is an entry into the Gada Prize. Following, our design goals match the prize requirements. Unique ones for Lewis are as follows.
- Fit into a small flat rate USPS box (about 220mm x 135mm x 41mm)
