Remix Dremel CNC C-Beam with Dual Rail

thingiverse

This is a Remix of my Remix, taking the dual rail idea even further introducing a C-Beam instead of two separate rails for the X-Axis. The C-Beam aluminium profile supports two MGN12 Rails across the length of the X-Axis. Currently 550mm in length with 450mm of useable work area.
