Warning! This design require particular attention on insulation of Hot End because of proximity between Hot End & Effector Structure. See the dedicated picture of insulation by special cotton and kapton.

Fullbody Effector for Delta Kossel structures:

  • 3 x 30mm fan ventilation, same flow on hotend & print.
  • Optimized cones for IGUS KBRM03 Rodends.
  • Compact frame with minimum necessary taken space.


  • Optimized air flow on the nozle with dedicated support
  • Closed 1 of 3 air flow holes in proximity of always On fan


  • After many requests, released the source of the project compiled in SolidWorks 2014

Nice design, but i wonder if there is any chance to get the 3 fans connected to the trigorilla 3d mainboard?

What are the screws used to put this model together?

7 of M3x10mm for the hot-end clamps and lower ducting
12 of M3x16mm for the fan mounts
6 of M3x25mm for mounting the rod arms
6 of M3 nuts, also for the rod arms
Hope that helps :)

Hi there,

I have made ur Kossel/Delta Fullbody effector. It works really great and love the fact that it is so compact. But for me there is a mayor downside when i print at low speed the product side where the heaterblok is gets a bit inaccurate because of overheating. Do u have any solution for me? i already have the blue Silicone Socks from e3d but still there seems to be a bit of overheating...

any help is appreciated,


I never tried the blue Socks, and honestly do not believe in a great solution of silicone for heat containment. You can see by pictures and advise on summury that I implemented the more traditional and mostly strong solution of the insulating cotton and capton tape. With that solution it's so greatly insulated that you can touch with your fingers the kapton sock when inside the heater is at 220°, consequently cant be a problem for the print. You must to close accuratly the kapton sock around the heater to insulate it from all the sides, in order to not create problems for the effector itself.



I found the problem. because of the silicon sock the air was blowing to the side of the heater instead of the product. I raised air flow and now it seems to work just fine. But as always there is a other problem... After the installation of the new effector the x and y dimensions are off. (like 4% or some). the z axis seems fine.. u have any idea how to solve that problem?

Ty for previous response ^^

(N.v.m found the problem the 25mm DELTA_EFFECTOR_OFFSET was not correctly added.)

I'm glad you solved your problem, pay particular attention on configuring DELTA_SMOOTH_ROD_OFFSET:


When it is wrong you have the anomaly like in the previous picture and also the rendered dimensions problem. When it is correct and the effector remain completely flat moving along the plate, also the dimensions will be completely right.

summury updated

what is effector offset ?

I'm curious - What did you print the effector used in the above pictures on? The print quality is outstanding!!

Hi, with the same machine of the pictures and with the same effector. The gol of a good print quality is in good mount, calibration, configuration but above all the rod end joints & linear guides quality or rather: mechanics quality. The precision comes from precision.

This looks very neat, great!

can you (or someone) recommend a silent 30mm fan? I have great mute 40mm ones, but couldn't find a 30mm one. After finding those, I'll switch over to this design.

Oh, and is there a way to guide the cables through so they come out alongside the bowden tube without looking ugly or disturbing the air flow?

Hi, I solved it like in pictures up, with a black indipendent cable group that go to the board. I think that the common commercial 30mm fans are all similar for the noise level.

Okay, I think I'll have a try.What kind of special cotton did you use for insulation? And in one picture you wrapped the heating block in orange tape, is that also kapton? And is it in addition or in replacement of the grey tape in the upside down picture? It reminds me of the official blue sleeves, shown here: e3d-online.com/image/cache/data/Socks/v6-3mm-Sensor-Block-cutout-24v-1000x1000.jpg
they seem not to be on ebay, though

You can find that cotton insultation on Ebay in form of stripes. Yes I used additional kapton tape to keep togheter the cotton stripes. Ignore the grey tape, it was a test, to see if it can be enough, it failed! :)

Thank you for the nice design , i added the auto level system feature to it .

Good work, I'm not a fan of auto levelling but for those who like that solution it's a good remix! ;)

Thank you for sharing, it is really nice design. I would try to print and install it into my kossel mini.

You are welcome..;) keep particular attention on insulation of the HotEnd. That improves also the stability of temperature of the same and optimize the energy drain.

nice design. just dommage dosent have autolevel with endoff switch.

check out the one i modified to use the auto level system .

I'm not a supporter of bed autolevelling. Beacause I think the quality of printing must to be searched in a Good manual & Structural calibration of the machine. For this reason I have not spent time in Autolevelling supports.

any chance I could get the solid model from you? I really love this design, but I would have to make a few changes to fit my printer. a solidworks model would be awesome ;)

Hi, if you check, now there is the downloadable source file between the Thing FIles.

thanks for very nice design - but, I'd like to separate two fans whit wall since I think it is not good to cool some materials (ASA, ABS ....) during printing.
So, is it possible to share source files? Does not matter which 3D format, I can work with almost all of them.
Thank you very much

Hi, if you check, now there is the downloadable source file between the Thing FIles.

What do you mean? This structure implements 3x30mm fans into the same air flow room, that results, in my experience, more powerful that the classic 2x40 separated flows design.

Nice design. What are the screws needed?

nice design,
what is the distance between the rods?

Hi, 40mm like Kossel standard.

under 40mm fan

thank you,
is there a way to add room for the auto bed level switch?
i would love to get the SW model if you can send it to me.

Let me your email, and I will send you the source.

Please help me, I use 1 fan 30mm and 2 fan 40mm

This design it's provvided of 3 - 30mm fans, it's strictly forced by rod horizontal standard offset of 40mm. There is no space for 40mm fan with this solution.

Hi Kirill,

You have designed a great effector but few modification I would like to make to this effector.

  1. I just want 2 fans (1 side) for hotend (2 side) for cooler, so I will add some kind of wall between hotend and cooler, because in some case I do not want cooler for some print, so I can switch off the cooler, with your design it is not possible to turn off the cooler.
  2. I will add infrared sensor for auto leveling to 3rd side wall and will mound sensor board close to the hot end and some cables holder for heater wire and thermistor (like this effector http://www.thingiverse.com/thing:1252945 )

I especially designed 3 fans with the same flow canal beacause I retain it works good. 1 fan attached directly to power source and 2 fans controlled by firmware. This frame idea comes from Kosel Pro design. To do your solution it's faster design another indipendent frame that modify this one. There are too much dimmensional thresholds in this one that I overcomed by a hair, by considering the specified hotend, fans and rodends space occupation. This is the best compromise for this solution.

Best regards,


I agree with you, your design is really good, does bottom air flow makes hot end cool down? I used 40mm fan cooler for my kossel build diy printer and my print layer did not stick properly when I use cooler, so from now on I print without cooler.

I am planning to redesign my effector based on your design.


I think is the best solution. Take in mind that the key for a best sticking is the warm plate, also for PLA. Any cooler take in tension the hot end forcing it to more work but this stabilize the temperature, in my experience.


I it possible to have source file for this effector? width is bit bigger so I wan to modify to fit for my mini kossel printer.


Hi Riz,

In wich format do you prefer il. It designed with Solidworks. What exactly its bigger?


I can work with SolidWorks, but nomally I use FreeCAD, your model is 4-6mm bigger from all 3 sides, can't attach screenshot to this comment :( can I send you screenshot via email also the effect stl file which I use for my printer, so you can measure the size.

Also my effector rod pitch is 38mm, your one is bit bigger.
