Z Camera Mount

Ender 3 rear-mounted Z-axis camera mount, because I couldn't watch the nozzle on tall prints, and my EZABL Pro was in the way.

This thing positions the camera at the rear of the printer so a) it's out of the way, and b) prevents the ABL probe from blocking the view of the nozzle.

You need to buy:

1 - 2040 extrusion of the desired height (I used a 500mm extrusion)
1 - MGN12 Linear rail of the appropriate height (I used a 450mm rail)
1 - Dual z-axis stepper motor kit.

Parts:

0) Extrusion bracket - this attaches your purchased 2040 aluminum extrusion to the right/rear of the 40mm extrusion already on your printer. It is assumed that you'll be attaching the 2040 extrusion at the rear-most location (as illustrated in the assembled pictures provided. You will need M4 screws/t-nuts to bolt this bracket to the extrusions.
