The OpenBuilds Sphinx (assembly required) is a super strong, accurate, and easy to assemble CNC machine.

The Sphinx's design takes advantage of the inside tracks of the C-Beam linear rail using Xtreme Mini Solid V-Wheels, and utilizes Xtreme Solid V wheels on the outside of the extrusions. This design keeps the lead screws directed towards the outsides of the machine to reduce the likelihood of shavings contaminating them or the V-wheels. member Kyo was the originator of this awesome open source design!
