      Ah.
      O-ring recesses in a hole is going to be a bit difficult then... maybe a press-fit plastic seal might be possible though.

      Isolate, substitute, verify.

        @theruttmeister how about some (silicone) glue instead of o-rings to make it water tight?

          In an enclosure, a watercooling is the best solution for me. A chimera might very large for a single extruder. I drilled some blocks of aluminium used with the e3d heatbreak.
          No more heatcreap with a very small block 15936391776921731898753787276774.jpg

          15936392269301246707830868041104.jpg

          All the parts in the watercooling are in aluminium
          The first block had a thermistor in it and the mesured temperature remains at 27deg in a 60deg enclosure.
          These blocks were made with a drill.

            @tech-raton I am having a bit of a problem visualizing what you have done there. I see the heater and you say you use the E3D heat break so I am assuming that the heat break screws into your cooling block ? I am not sure what the red thing is in the square aluminum tube. How does the filament get guided to the heat break during a filament change ? What is the path of the coolant in that block - is it simply a blind hole at the entrance and exit with a cross drilled path connecting the two blind holes that is then plugged with the bolt shown in the middle of the block side ?

              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.

                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.

                              Thanks! I'll have a look at this block...

                                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).

                                      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.
