EDIT 09.07.2017 - Add 124a, 126a and 126b for small printers. Therefor now you need 3x 124a for an normal 124 and 126a + 126b for an normal 126.

EDIT 20.06.2017 - I've named the wrong ball joints. Uploaded new instructions.

Das Projekt PistenBully entstand an Weihnachten 2016, als wir so einem Monster bei der Arbeit zugeschaut haben. Die Idee ist eigentlich, dass der Bully irgendwann noch eine Schneefräse und Anbauteile bekommt.

Das Design ist angelehnt an den PistenBully 300 und 600 der Firma Kässbohrer – ich hoffe die sind mir jetzt nicht zu böse dafür.

Das Design ist simpel, alle Komponenten können in PLA und TPU selber gedruckt werden. Stützmaterialien: entweder selber machen oder meine Designs entsprechend verwenden. Spezialfall ist die Kabine. Hierbei habe ich bereits einen Druckkeil für den oberen Kabinenbereich modelliert, welcher nach dem Druck entfernt werden kann. Somit ist nur noch Stützmaterial für den unteren Teil notwendig. Alles weitere inkl. der für die entsprechenden Bauetappe notwendigen Komponenten werden in der Montageanleitung aufgezeigt.

Das notwendige Equipment habe ich inklusive der Lager von Banggood geordert. Gibt’s aber auch bequem beim Händler vor Ort…

Viel Spass beim bauen und truxen…



The project PistenBully was started at Christmas 2016 while we watched a monster at work. The idea actually is to get also some snowmill and attachments for it.

My design is based on the PistenBully 300 and 600 Kässbohrer - I hope they are not too angry on me therefor. But they’re really cool!!

The construction is simple, all components can be printed in PLA and TPU. You can choose to do the support by yourself or use the one I’ve done in the designs. Except for the cabin. However, I have already modeled a part for the upper cabin area, which can be removed after printing. So support only for the lower part is necessary. All further details are shown in the assembly instructions (PDF).

I’ve ordered my equipment including the bearings at Banggood. But it is also available at your local dealer...

Have fun and enjoy!

I'm finally done printing and have started the build of this wonderful machine, I'm still amazed by the quality of this model.
However....the springs seems to be a bit short or are they supposed to be stretched?

Yes, they should fit really tight. The reason therefor is, that the whole truck weights around 2 to 5 kg, depending on your payload.
But it is also possible that they come out differently with different materials and/or manufacturer. If so just stretch the file a bid (0.5mm) in your slicer, that should work to...

Thanks!! I'll try to print with Another flex I have thats a bit softer. I'll have to see when I get the bearings as well because now I barely can get it to align with the holes of the axle.

Thanks for sharing! I wanted to have this snow remover for a long time. Like the one made by kyosho for > $300 USD.
May I ask what is the name for the last ball-shaped screw in Schritt 1(Where you listed 0 5mm 24x, but in the diagram below you mention it is a 05 M3x8)?
I am confused by the different names, and I cound not find it anywhere. Do you think there is any alternative for it?

Hi 897846, thanks for the Like. I think you mean the Ball Head Screws? I'm not 100% sure, but I think I've used those: https://www.banggood.com/Wltoys-A949-A959-A969-A979-9_3x5mm-Ball-Head-Screw-10Pcs-p-978871.html?rmmds=myorder

Sunny regards, Peter

Yes, this is what I meant. Thanks!

Hi, whats the torque available at the output of gearbox with this BLDC motor?

Huuu, I have not measured it so far (no equipment therefor). But the Bully takes 100% incline (45 degrees) fully loaded with 2kg extra weight (sufficient liability provided).

How did you place the cabin for the print? I'm using S3d and it uses a lot of filament for support of the cabin, 800g to be precise, the cabin it self is just over 200g

Hello Sweden, Switzerland is speaking.... lol ...and for the rest of the World (USA): no, that's not the same..... :-)

Sorry, out of topic! So to your question - true. I've printed the whole cabin in one piece, and because my S3D/Printer Combo couldn't handle with those supports I decided to do it by myself. And this is where the whole PLA stuff is going for.... :-/ ...not sexy, but it works. I've added some pics where you can see how I place the cabin on my printer (which by the way comes from Sweden.... :-)

Today I would probably prefer another solution with two-part cabin and some glue... hmmm, have to think about it...

Btw. with S3D 4.0 you should be able to do the support with some different settings by using the "different settings wizzard". Just an idea...

Aha, hello other Sweden from other Switzerland :D

I've spent a while with S3d and the cabin and I think I have a solution that saves a bit of filament but it means splitting the cabin, I'll get you some pictures of it but first I have to convince my main printer to start working again, it thinks it can take some time whenever it want to so I have some convincing to do ;)

If you decide on making proper a split cabin, I've tried in Sketchup but it's not easy to work stl files, please let me know, I think a cabin in two or more pieces would be much easier.

It's a damn nice model you've made, it's easy to tell that there's a few hours behind it and once it's done I'll be sure to send you some beer money for you effort. There are however one thing, it's not all printer friendly ;) some parts take a while to position in a good way to get them to print good.

Beer sounds good....

Since I've made the last months a couple of small projects with very small walls and therefor very little amount of PLA and a lot of CA I would made the PistenBully different today. Guess it's always the same with that *** learning process... :-/ :-) ...the problem is the Rooftop. If you cut it away and print it alone it will be fine. But then you will run into problems with the window profiles - at least I did. My printer doesn't handle fine segments pretty well, or I don't know how to do it the right way. Maybe I'll have an idea at the weekend... (Note to me: Put beer in the fridge)

And yes I now, not all parts are printer friendly - at the time I designed the PD (Xmas 2016), I did not know how to define a different coordinate system for STL. Well, I do know now, but's still a lot of work to redefine almost 200 parts... (more beer?)

Let us know how your project is going on! :-)


There's always a learning curve and a project like this I can imagine isn't something you can just change one bit on because one bit here means two bits there and one on the next bit and so on. But you learn and next project gets better and then you learn even more and that's part of the fun, your own personal development.

I've ordered most parts and are halfway through printing the first bits and found the issue with my second printer so once that's fixed I'll try to print the cabin again.

What size and specifications do you have on the servo, when I search for mid size I get many different sizes.
Have you tried making the plow turnable?

I know I shouldn't question you since your sort of German, just more peaceful, nut are you sur this is a 1:14 scale model, it's HUGE!!!! :D
Anyhow, in the instructions you've listed a few things wrong or you've named them wrong, for example in the instructions you name the 118 as the one for 10mm bearings but in the files it's the 118a that's for the 10mm bearings. Same with the 120 Pulley halter
I do think most people with 3d printers are capable of figuring these things out but for the sake of things being correct you might want to look into it :)

Uhhh, really? Thanks for the hint, I'll check it next week...

I printed the cabine in one piece, just before the update of S3d to version 4.0.0.
It took 65 hours of printing and had 1/3 of the filament used by supports.
I'm almost finished, only have to print one site of the track.
Now mounting the lichts and blinkers and waiting for the engines (backorder untill end of september).
I'm going to build a cabin on the back to put a large battery in it to power the PB.

Aad Koene.

Almost about to start printing the cabin, got the yellow filament today so I can make the machine more Swedish looking, I'll try to remember to take som pictures and post a "I made one" later on.

Supeso you mentioned that your printer are from Sweden, did you by and chance by it from 3d Prima?

I've taken the liberty to remake the split tracks, I made on that are 2/3rd of the original one so I don't have to print as many, I also feel that less joints makes for stronger parts, you'll just have to print one small track for each side this way. I'll be glad to upload it as a remix if it's okay by you once I know it works and fits :)

you have snowblower project for your pistenbully ??
thanks ;)

Jupp... but the designprocess is still in progress...

nice :D
i want one for my beast rc4wd

This is just briliant, this is why I love the 3d Printing World, all this effort and then just sharing it with everybody. Great work my friend, I'll get started printing this as soon as I can but I'll probably try to make it 1:10 since I'm into all this scale rc and have a bunch of 1:10 cars already :)

1:10 sounds like a cool project!! But I'm not sure that all parts will fit after scaling. And some parts are going to be biiiig.... but let us now how it works! 8-)

Hehe, I posted this while at work, I hadn't had the time to check the files and well, I'm sticking with 1:14 for now, I have one of those small printers, a Wanhao i3 so I'm limited as to what I can do. I'll probably look inte to 1:10 later when I have a bigger printer but for now the 1:14 will do just fine :)
The whole fitting stuff and finding bearings, belts etc are another reason why I'm not doing a 1:10 now

Awesome project, I would also need smaller 126 and 124.
I'm printing it on Ultimaker 2+ which is 223x223mm.

Supeso - in reply to 2ndalpha

Ok, I've uploaded some new parts -> 124a is a third of the original 124, so you need 3 times more parts and some more screws (I know, it's not the sexiest way but the fastest at this point). And with 126a + 126b and some screws you get 126...

Oh boy, always those little cheapyprinters.... gg

But I see the problem and trying to fix it. Not a big problem on 126, but 124 is a bit more difficult. Because this part has an exact length and distance of the segments. I think a totally new design would be the smartest fix, but therefor is no time at the moment. I try to cut the part to a third of the original, so that should work... you need some more screws then... :-)

Hallo Supeso,
echt cooles Teil !!!
Hab aber ein Problem mit 126_-_SchaufelMitte und 124-_Raupensegment leider ist mein Drucker zu klein :-(
kannst du bitte die Teile in der Mitte teilen und 2 Teile daraus machen
oder die STEP-Dateien hochladen ?

Danke im Voraus

Jul 9, 2017 - Modified Jul 9, 2017
Supeso - in reply to Woipadinga

Habe mal die Teile gesplittet. Die Schaufel 126 gibt es nun in 126a für Rechts und 126b für Links. Einfach mit 2.5er Schrauben zusammenschrauben. Die Raupen habe ich auf einen Drittel gekürzt, damit es in der Summe wieder aufgeht. Somit sind nun 3x mehr Raupensegmente notwendig (und ein paar Schrauben mehr), hoffe das passt.

Ohhhh. Ist das so gross? lach

Werde eine Variante zweiteilig machen sobald ich zu Hause bin.

Super danke !!!!!!!!!

Do you tink you could make an english version of the Pdf?

Jupp I know, it's "work in progress". Hope I can do it this weekend...

But mostly should be understandable with the pictures or am I wrong on that?

It is understandable with the pictures and google translate ;)

I was looking quite a long time to build this Pistenbully but couldn't find it untill you came along.

Thanks for posting this one !!!!

Thanks for your "Like it"... :-)

I'm happy when others have pleasure too...

You have made a awsome work with the instruction. But I'm new to the rc world.
It would be good with a list of what drives the Pisten, maby a instruction what motor is needed and how to wire it up.

Hi, thank you. And welcome to the awesome world of RC-Stuff... :-)

Good point, thank you for your hint. I'm using this Motor/ESC-Combo (need 2 of them): https://www.banggood.com/Racerstar-2838-Sensorless-Waterproof-Motor-36004500KV-35A-ESC-For-112-114-Cars-p-1056318.html?rmmds=search

The Wire-Thing it's easy done, just connect them together as on the pics shown. You can eather run both on a separat 3S-Lipo, or use (like I do) an Y-Adapter. (Picture: https://www.dropbox.com/s/swqj6ljlhyepdqj/IMG_2414.JPG?dl=0 )
The thing about the RC and how to control the pistenbully is a separate story - many different options here. I'm using a Spektrum DX18 (Stick-Controll) Steering. Option 1: connect one esc to throttle an the other to elevator an controll the thing with to sticks like a dredger. Option 2: Use the elevon-mix on the controller to mix both esc to one stick. That's what I did because I want to controll the shovel with the other stick. Therefore connect one esc to elevator and the other to aileron. (Picture: https://www.dropbox.com/s/6bby1puo7krwfre/IMG_2415.jpg?dl=0). The Butterfly-Mixer would work therefore too, but in my opinion it is a bit more complicated to do the mixer-stuff. Option 3-10: feel free to find a way that works for you and post it here... 8-)

3600 KV or 4500 KV is better for Pisten?

I'm using the 3600... you can change the gearspeed/ratio by using different pulleys (there should be some "optional" pulleys in the STL-Files)

can you post the link of ball joints?

Supeso - in reply to gale9010

Sure. I can't remember where I bought mine, but those are identical: https://www.banggood.com/Wltoys-A949-A959-A969-A979-9_3x5mm-Ball-Head-Screw-10Pcs-p-978871.html?rmmds=search

Btw. you're right, the assembly instruction was wrong on that point. I've made an new update... (still should do an english version... :-( )

Evtl. kann man hochscalen auf 1:8?

Jun 10, 2017 - Modified Jun 10, 2017
Supeso - in reply to Renngarage

Danke Dir... :-)

Das mit dem 1:8, infolge eines Rechnungsfehlers habe ich in der Tat ursprünglich mit 1:8 begonnen - die Raupen und Seitenteile wären schon vorhanden. Allerdings ist das mit dem "einfach" hochskalieren so eine Sache - die Bohrungen, Lager etc. müssen trotzdem überarbeitet werden, sonst passt nichts mehr. Dauert schon noch ein bisschen.... und bis jetzt stecken in dem Projekt bereits um die 100 Arbeitsstunden oder mehr. Aber bald kommt ja der Winter, im Juli schneit es ja häufig.... lach ...dann will ich auch mal den Part mit den Fenstern noch fertig machen sowie etwas an An- und Aufbauteilen konstruieren...

I have to build this too, only bigger. Much bigger. Enough to plow my driveway bigger....awesome.

Sounds like a good idea....

Wow excellent! I'm ordering bearings and warning up the printer!

Thank you...

Thank you, this one I must build.

Let us know how it works!
