FLSUN Cube Carrage and Z limit. (part cooler updated)

This is my design on a carrage and z limit for the Flsun cube printer. All (complete) files should print together. Also included is a remix of a X bearing holder you will need. (M4 nut and bolt required.) supports a part cooling fan and makes the overall print volume 270X270X360.

You will need-
1X M4 nut and bolt for X bearing.
M3 nuts and bolts that come with the printer and I had plenty left over for this project.
V6 J-Head extruder, NOT THE ONE THAT COMES WITH THE PRINTER. Clones can be had off the bay for under £10 if your on a budget tho, please support E3D if possible.
40x40 part cooling fan.

The reason I used a E3D hot end is because its shorter for one, giving you a little more print height, but the main reason is the teflon tube goes all the way down inside the cooler unlike the one that comes with the cube, eliminating jams and if you cange your extruder gear you can print with TPU. Bonus.

The linear bearings just push in and click into place. Trust me they are hard to get out once in. I used DryLin bearings as they make no sound.
You may want to leave the 4 bolts holding the rear bearing loose so theres some give if the Xrods are out slightly. The Z limit, you need to tighten an M3x25 through the adjustment wheel and clamp it between the two halfs on the clamp, push a nut into the slot on the top hat and place on top the screw down with the wheel.

Here are the changes I made in Marlin. You may need to tweak these but they work well for me.

---Auto bed leveling---
GRID_MAX_POINTS_X 2
LEFT_PROBE_BED_POSITION 45
RIGHT_PROBE_BED_POSITION 240
FRONT_PROBE_BED_POSITION 45
BACK_PROBE_BED_POSITION 240

X_PROBE_OFFSET_FROM_EXTRUDER 30
Y_PROBE_OFFSET_FROM_EXTRUDER -30
Z_PROBE_OFFSET_FROM_EXTRUDER -0.6 (Gives enough clearence from the bed with a glass top, I used an Ikea mirror)

If I think of anything else I will update.
If you make one please share on here + remixes.
Thanks and happy printing.

Replaced the single file of the part cooling fan for a better version.
Bigger mouth on the exhaust and thicker walls.
