      Here is what I planned to do for a friend:

      The heatbreak is not the standard one, it is a full M6 thread, instead of the standard M6/M7 one.

        @tech-raton I am not sure what the red thing is in the square aluminum tube.

        A remote extruder, I think.

        @tech-raton, what is the hotend, on the delta? I like round the heat block... Is it a piezo, above the water cooling block?

          OK so the water cooling block is a straight through drill and then a loop on the far side back into the cooler ? The ptfe tube goes straight to the heat break ? I assume the top thing is the ptfe coupling ?

          Is the nut captive somehow in the assembly ? How ?

          Sorry about all the questions ....

            Yup the red thing is a remote extruder.

            The watercooling on the corexy is just a 8mm aluminium part with 7 holes drilled
            A m7 for the heatbreak
            2 m5 for the pushfits
            A m4 to connect the 2 m5 holes
            3 m3 holes to attach on the carriage

            On the delta, the hotend is a maxiwatt with a homemade silicon sock
            And yes with a piezo as z probe

            Why you heat

                Why have 4 pushfits?

                You could make a u shape inside your watercooling.
                It will reduce the flow but will increase the heat exchange.

                  Exactly.

                  The ptfe tube goes straight to the heat break ?

                  Yes.

                  I assume the top thing is the ptfe coupling ?

                  No, this is the standard groove for hotends. It is designed for direct extruding. But you can modify this part (3D-printed) for Bowden, using a coupler thread.

                  Is the nut captive somehow in the assembly ? How ?

                  The 3D-printed part is made in 2 parts (split along the vertical axis), and glued together (there are 2 holes to help aligning it. Here is a closer view:

                  Sorry about all the questions ....

                  You welcome! This design hasn't beed tested, and I would love to have feedback if you go that way.

                    Easier to do.

                    You could make a u shape inside your watercooling.

                    How? I only have a drill...

                    It will reduce the flow but will increase the heat exchange.

                    It is the same, as I use a small external tube to make the half turn.

                        Ahh, clever! If the ptfe tube is captured by clamping pressure that seems to make clearing a clog kinda tough ???

                          As said, I didn't test it, and it may not work as expected. A longer heat break should be better, but I'm not sure if we can find one... But yes, the PTFE tube has to be clampled down, with the above part (extruder or bowden push fit).

                            Well I think that it shows great promise!

                              The goal of this design was to be able to use it in a standard setup (groove), but if you can customize the extruder side, it might be improved...
                              Another thing to check is if the 3D-printed part can handle the temperature. It should if the water flow is good, but better use PET-G or ABS.

                                Do you have a CAD design of your setup, with Piezo? It is a nice and compact solution...

                                  With only a drill (and a screw), you could have a u shape.

                                    @fma yes i think i have it.

                                    What kind of files do you want?

                                    I work on catia

                                      Ok, I see for the U. I will do that the next time!

                                      STEP is ok for the CAD files. Thanks!

                                        Do any of you guys have any links to the tube, fittings, and pump that you use. I'd like to use the smallest possible tubing and the quietest possible pump.

                                          I'm about to test a car windshield water pump, for which I made a custom tank. I don't know if it will last long if on all the time, but it was on my old 350000km car, and still working fine! I think it is unbreakable 😉

                                          It has very small outputs, good for 2mm ID silicone tubes. The nice thing is it has 2 outputs (front and rear windshields), depending on the rotation direction of the pump, it sends water on one or the other.

                                          See :

                                            @fma Those things tend to be bloody noisy. You don't really notice it when it's fitted in the engine bay, the other side of a bulkhead covered in sound deadening material. I don't think I could put up with one of those screaming away continuously, but let me know how you get on with it.
