Flsun i3 Z carriage and screw upgrade

This is my design of the z carrier on the Flsun i3.
its inspired of another design on the x carrier that i liked alot to match all the carriers. https://www.thingiverse.com/thing:2521909
my remix https://www.thingiverse.com/thing:2800992
you will need all parts! carrier dont work with standard z screw mounts!
i put the steppermotors on bottom for stability
right z carrier need support if your bridgegame isnt awsome!
I really like the feel of the whole design and it works good
