KP3S dual fan duct for 4010 fans

thingiverse

In addition to my other fan duct designs for the KP3S I created this little guy here that uses two 4010 radial fans for part cooling and one 4010 blower fan for coldend cooling. It is mainly designed for V6 hotends but should work as well with the original hotend (see below). Upon request of some users in the KP3S Facebook group I upload this part here already. The fan duct is bolted to the original 30 mm fan clip and for the ease of use fastend to the rest using hot glue as it is more or less still a prototype. But this prevents it effectively from vibrating. To use it with the longer original hotend it should be suitable to just rotate the fan clip with its extending edge showing downwards. For the V6 hotends that edge has to face upwards! To have enough clearance for the fans and everything the fan duct is turned a bit around the z axis and having a chamfered edge at the rear left. At least on my setup with TriangleLab Titan Extruder this still leaves enough space for the x axis tensioner. So do not wonder why it might look a bit wrong. The 4010 radial fans are fastened by using M2x5 screws on the top holes. For mounting the 4010 blower fan and the duct to the fan clip you can use M3 screws or self-cutting screws that mostly come with those fans. Length varies with your used fan.
