Bought a cheap QQ-S Pro to mess with and wanted to mount a Creality Unicorn Ceramic Hotend instead of what was stock on the FLSun.

It's designed for the Creailty Unicorn kits built for the Ender3v3SE/KE so it's form factor is MK8, use the lower two holes.

Technically it works with any MK8 based hotend (so you could use that cheapo red one from microcenter if you really wanted to).

Sadly the last owner did some questionable mods and really messed up the wiring and while attempting to clean it up I blew up the mainboard's CPU. So the printer is now collecting dust while I attempt to figure out what to do with it.

Either way the mount works and for the short few minutes the printer was working it was fine, I believe the rear fan kinda rubs on the carbon rods so you might want to switch that out with a thinner fan.

It uses threaded heat inserts for the mounting hardware, M3 and M2.

When you mount the Unicorn hotend, the nozzle is at the correct height for the stock fan ducts so no modification needed.

Recommended to print in ABS/ASA, PLA/PLA+ might work but I wouldn't trust it for a long time.

I also included an adapter plate for hotends that don't have a way to mount the PTFE tube, for example the Unicorn nozzle doesn't since it's normally ran on machines with direct drive extruders.

The printed version in the photos was printed at 0.6 with Inland Green ABS on a K1SE.
