Evolution X-axis carriage for FLSun i3 (integrated tensioner, v6 clamp mount)

-Integrated belt tensioner -E3d v6 clamp mount -Slotted bearing mounts -Improved cooling -Improved nozzle visibility with v6

Upgraded X-axis carriage for the FLSun prusa i3. Remixed the original FLSun model adding an integrated belt tensioner while retaining original fitment and functionality and trying not to add too much weight. The tensioner uses an easy slip-in belt clamp and M3x35mm bolt, captive nut, and washer.

Newest "Evolution" version fits uses a clamp mount with m4x25mm bolts and captive nuts for the e3d v6 style hotend mount. Nut holes are modeled square to accept the square nuts that came with the kit or normal nuts. It moves the hotend mounting point 5mm forward and clearanced so the v6 heater block can be oriented with the long cartridge clamp end towards the rear, allowing better visibility of the nozzle. Y-endstop needs to be adjusted 5mm forward to match.

Included is a little Y-stop spacer that gets rid of the nuts used as spacers and gives the option of relocating the stop by 5mm.

Because the rod holes in the original z-carriage blocks appear to have been eyeballed a bit too deep, or have no end stop at all in the case of the top left, the belt can pull the z-carriages together and the load is put on the z-rods which flex at the center. Clamps are needed on the x-rods just inside the blocks, or use my z-carriage blocks (https://www.thingiverse.com/thing:2288811) which have the holes blocked at the correct depth, to put the load on the x-rods.

If You make it, please post it!
