FLSun Q5 Universal V6 Effector (5015 Blower)

UPDATE 2: Increased the size of the counter screw hole and around the hotend mounting groove to fit M3 insets. Old files for self-cutting screws still online. These may need some re-tightening every couple dozen hours of printing.

UPDATE: The effector plate was wobbling due to the gap for the thermistor/heat cartridge cables, so I removed the gap. Printed it in CF PLA and it's rock solid now.
I also moved the screw holes for the probe holder closer to the nozzle, to mitigate the X/Y offset. 

Clarification: There are 2 5015 blower holders. Part_Cooler_Adapter_remix is usable with the provided cooler duct. Part_Cooler_Adapter_remix_Classic_Duct should be compatible with the modular system that is popular and fits most designs. The only difference is the heigth of the mounting point.

As I was hellbent on getting the most out of this printer, I wanted a lightweight effector that was able to hold a 5015 blower. As I had problems with other designs, I mashed two of them together:

Effector:

Blower holder:

I made adjustments to the blower holder, so I could fit the stock Q5 hotend, which seems to be significantly longer than the normal V6 (or the positioning within the effector is lower).
Also, the screw holes on the blower are doubled and moved higher/lower to accommodate the mounting plate.

In my experience, the magnet holder is too tight to fit the threading shafts, but I forgot to save the STL. Just load the STL in something like Blender and scale the holes to ~4.3mm diameter.

For a BoM, see the Thingiverse link to the effector above! And a 5015 blower, naturally. Probably buck converters.

I printed mine in CF PLA (Extrudr GreenTech Pro CF) and it is rock solid.

Use 3-4 perimeters in all parts to ensure stability.

Hotend Mounting:

The hotend got a little loose after some dozen hours of printing, so I re-designed the cage to fit M3 insets. Also, I removed 1mm of material around the groove so I can press-fit it together for a rock solid print.
The hole for the counter screw in the hotend cooling mount now also fits an M3 inset.

Fans:

For the hotend fan, you can use the stock one. It's noisy, but it gets the job done.
The 5015 blower will most likely require you to wire in a buck converter to reduce voltage from the mainboards 24V to the 12V most fans use.
As I was already on it, I changed all fans, which resulted in an extremely quiet print (except for the 5015, that thing is LOUD). 
I will need to tinker around with the fan speeds, as I fear that the cooling is now TOO powerful and could affect layer adhesion.

Z-Offset:
Finding the correct settings for the Z-Offset was tricky, as in my implementation, I squeezed the threading shafts of the magnet holder INTO the holding block. This offset the probe, so be sure to correct it in your firmware!
My settings are: X-0.5000 Y-1.7000 Z-18.63
As it's a female dog in heat to input this into the closed source Repetier fork FLSun uses for the Q5, I flashed Marlin 2.1 (Thanks Foxie!) to get a consistent printing experience. Without this offset, my printer had issues with printing too close to the bed in some parts of the bed and completely fine in others.

Fan Duct:
As mentioned before, use the “normal" part cooler adapter for the duct provided here or the classic_duct design for the popular modular system.
To prevent the duct from falling off its mounting point (happened a lot), I fixated it with a standard Nylon ziptie. It can withstand the heat and you can push it upwards to change the duct later (see pictures).

The CF parts were printed on my friends Prusa i3… that thing is a beast and extremely accurate.
