Cnc Mill using standard and 3d printed cimponents

I used the cad designs for the c beam to find a solution to my initial sourcing problem. I figured that I could use 2x 20x20 and 1x 20x80 Profil to create a c beam actuator. I sourced all of the profiles from a local machin builder and t-nuts and screws in my local hardware store. Some parts are currently in 3d printed pla for testing reasons.
