    Oh wow that was some fast shipping. Things get to the good old USA from Sweden a lot faster than things from China. Well I am still waiting on the geeetech 3 in 1 mixing hotend before we can get started but check out these extruders..

    Well the BondTech dual drive extruders are great. absolutely everything I expected them to be. But they did not solve the problem. And honestly I didn't think they would. While they do allow for applying a lot more driving force to the filament the diamond hotend still has a problem with whichever filament doesnt get used for a while binds when it starts getting used. I think the problem lies in the sheer amount of exposed surface area of the hotend vs. the size and location of the heater and the thermistor. I could be wrong, but that is what is driving me away from the Diamond hotend. I am all set to start getting this Geeetech 3-in-1 mixing extruder up and going with the bond tech and the blue ptfe tubes and just have a really awesome machine but don't you know that hotend is taking it's sweet time getting here. So I went and checked on the status of my order and I just wish I could have ordered this too from them Sweden. 2 month shipping time..

    Well it has been a while and I never got the Geeetech 3 in 1 mixing hotend from Banggood or bangood or w/e. It got lost in the mail. Tracking showed it moving to about half way across my state and it just stopped. I am less than happy with the whole thing but I was trying to flesh out a good multi material printer and so I have ordered this part again. This time from a different source. Also I kidnapped one of the genuine Bondtech BMG extruders for my coreXY build and have replaced it with a $20 knockoff. So I will be able to have a real world side by side comparison of the genuine and knockoff BMG extruders. I already have the extruder and should get the hotend in the next day or two.

    Oh ya. So the Geeetech built 3-in-1 hotend finally arrived. I am so excited for a newly designed 3 in 1 mixing hotend. The diamond hotend is such a frustration but I am thinking I will have a better go of this guy. And look at the size comparison..

    The Diamond hotend is a big huge chunk of upside down triangle with the nozzle being at the very bottom and a whole lot of surface area exposed and just one little 6x15mm heater cartridge at the top. The new Geeetech hotend has a more traditional nozzle and the heater block has 3 of these 20 watt 6x15mm heater cartridges so I know the temps will be more stable and accurate..

    I have found no mounts or anything for this hotend at all really on thingiverse. And so I will draw up my own mount and I guess it is better that way anyways. It will be a lot more specific to what I am doing. The cool thing is all the drilled and tapped holes on the top of the hotend for mounting..

    I tried to reach out to Geeetech on Facebook to inquire about purchasing the parts that secure the 3 in 1 mixing hotend to the carriage and not only did they not respond but they also deleted my post. Whatever their reason or position I spent over $40 on their product and was prepared to spend more. I was a customer and this was a bad experience for me in the name of customer service. Bad form Geeetech. And so I drew up my own mount for the mixing hotend trying to keep everything as compact as possible..

    My design puts a 40mm fan on either side of the heatsink in a push pull configuration..

    They will be wired together in parallel and set to come on only when the nozzle temp is above 50c..

    On the front face of my mount I have 4 holes and a big flat surface to mount a layer fan, ...when I design that. I like this hotend so much better than the diamond hotend. The nozzle size is 0.4mm and unfortunately that is the only size I have been able to find for it. One of the great downfalls to the diamond hotend is the fixed nozzle that can not be removed or changed. The nozzle on this can come out but 0.4mm is the only size I have been able to find so far. But there is at least hope with this one..

    I just have some light wiring to do and then some calibration stuff and I can get back to trying my hand at multi colored prints..

    So I have collected the 3 files that I have made to get the Geeetech 3 in 1 mixing hotend up and working in an i3 style printer. the i3 style home built printer i made these parts for uses Geeetech i3 pro B printed parts for the X and Z and so this carriage will fit any i3 style printer with the same spacing between the 2 smooth rods as what is in the Geeetech i3 printers. I still have to design a layer fan but i did leave a place and 4 holes to attach said layer fan when I get it drawn up. And I will add it to this: Geeetech 3 in 1 Mixing Hotend Universal i3 Mount by AutoWiz - Thingiverse
