Kingroon KP3S dual 5015 fan frame and ducts (3D touch update)

The design uses two 5015 fans with two fan ducts, one at the front and one on the left side.

[THIS IS NOT NEEDED, THE FAN FITS ON THE LEFT SIDE FINE] To make space for the left side fan duct the 3010 heatbreak fan has to be rotated to the right side of the extruder (blowing from right to left) and the heater and temperature sensor wires on the left side.

The mounting screws are M3 for the two fan ducts and M4 for the 5015 fan mount. The three frame screws that screw to the printer body are also M4. Note that the design allows some height adjustment for the entire frame.

The space for the two screws that hold the front fan is limited so short head screws are preferred.

To connect the second fan I removed the sticker at the back of the front 5015 fan and soldered the additional wires in parallel (be careful not to short the wires) but you can also bridge the wires externally if you prefer.

I have included two version of the frame, one with a C style cable holder and one with a couple of holes intended for a zip tie or wire.

The cable holder C clamp is intended to hold this part (you press it all the way down).

The second version has two holes to use a zip tie to hold the cable

How to print
--------------------------------

I have used PETG,  0.2mm layer height with 20% infill. My bed sticks pretty well so I didn't have to use rafts but you may have to depending on the printing material and bed surface.

I have used supports on the print bed only which works very well.

These are the setting I have used  (prusaslicer)

Update : With the 3010 fan on it's original place (the left side) there is room to fit the 3D/ BL touch sensor. X distance is +28 mm and Y distance is +1.5 (may depend on the angle that the sensor is screwed on)

I have added the 3D touch/ BL touch base model and a frame version that includes the holes to mount the base.
