I received my KP3s which came with Direct Drive as standard, as I wanted a second printer but a smaller one compared to my Ender 5, unfortunately build quality isn't great on the hotend unit, but it does have some positives on the rest of the frame.
The first thing I wanted to replace is the hotend setup with it's DD mash up. So I got myself a BMG/E3d V6 Clones but needed an adapter to fit on the Linear rail on the X Carriage.
After looking around decided to make my one, and here it is.
I would say this is currently a Work In Progress as I'm printing the parts and ensuring design is as good for others as it is for me.
With this design the bracket adapter does not need to be remixed if you want to change the fan type or shroud, also if you do not use a BLTouch this does not needed to be printed.
The Fan mount for the 5015 blower and the BLTouch mount can be adjusted up and down by 2mm in it is too high or too low for your setup.
My current setup uses the existing fan that came with the E3d V6 clone, but plenty of adapters to increase it to a bigger fan.
Update 02/05/21
I've noticed that I had lost bed size on X axis and Y axis, so to fix the X axis I've added a new limit mount for a M3x20mm screw so that you can adjust it and gain all the 180mm of the X axis, unfortunately it seems Y axis we lose about 8.5mm.
Still trying to work out design tweaks to give the full 180mm length, any feedback is welcome.
BLTouch Offset values:
Printed this with 40% infill on PLA, but you should be USING PETG for this as it will be close to the hotend.
The Fan mount can be printed without supports, however it depends how good your printer is tuned for bridging.
Make sure you flip the X Carriage adapter as there is 1mm square space for the Nema 17 motor.
The Fan shroud make sure you lay it flat at the bottom, so it will be at angle, no supports needed.
