Ender 6 replacement parts

Contains four replacement elements for Ender 6:

Z-axis bracket: maintains Z-axis vibrationless

Extruder housing: lightweight replacement to make gantry lighter and reduce ringing. Another thin I discovered is that a springed feeder allows some Z-play on hitting overextruded lines, reducing the stress on the table attachment and thus reducing risk of the printed part from popping off.

X-axis spring-squeeze roller plate: reduces wear on rollers, less damping on stepper motion.
20mm long conical M5 screws and original rollers used.

Y-axis spring-squeeze roller plates (print two).
20mm long conical M5 screws and original rollers used.

Overall, replacement reduces gantry weight by about 170 gram.
