Qidi Tech Linear Rod Supports

In an attempt to stiffen up my Qidi Tech into a complete brick, I recreated the end supports (shown sitting on the platen) to be beefier and longer.

Should be sized to produce a slight press fit on the 10mm rods. Will require new screws for the lower stepper and mounting.

Definitely improves the rigidity of the Z stage--especially on the first few layers. You can increase print speeds by 20mm/s and still get good corners and minimal z wobble.

Now, what to do about that flimsy X-axis...
