"Prusa Air" | Make:
I love the look of this Prusa Mendel RepRap 3D-printer fork designed by Thingiverse user Mecano. Shown above is a concept rendering of his second prototype, Prusa Air 2, which hasn't been built yet, and below, the physical prototype of Prusa Air 1. Among Manuel's stated design goals for the project were "a little beauty," which I daresay he has already achieved, admirably.
