4 linear rails (IKO), each is ~17"
2 ballscrews (THK)
Supports and bearing blocks (everything needed for assembling into two CNC axes)
1 linear actuator (NSK), ~27"

All components could be used to build a 3-axis CNC machine (3d printer or router).
One possible option is a fixed portal style, with the table being actuated by the NSK actuator and Y+Z axes via the linear rails.

See the image. Condition seems to be okay, but these components were sitting in a box for several years. Everything moves. There is some small amount of surface corrosion.

Price: free for grabs!
Location: San Antonio, TX (1 hour from Austin, TX).
