Hi does someone knows how to get this in to a printable design ?
I have the step and stl file.
Design by Simon M
I’m assuming everything in the picture is in the step files. For the body you have to make sure that it is shelled. If not then you need to shell it and then break it into slices where there is one flat side so that you can print it on your bed. Other parts (suspension), you just have to make sure they fit your bed (if they are too long you will have to split them), and then you make them into an stl file. Once it’s an stl you just check the part rotation and then start printing. Which CAD program are you using? This goes without saying, but just make sure to give the guy credit. It’s a pretty cool design.
I use Freecad and Soldiworks but i’m still newby to 3D printing
@Christoph_Derycker okay. Both of those programs should have a function to convert the files into an stl. If they don’t then you’ll have to convert it via a third program, but I would imagine that they do. Also check your sizing before you start cutting up anything. You want to make sure that your printed car isn’t out of proportions for your electornis, tires.
Oh and the rims will probably need grooves if you are planning to use store bought rubber tires. I’m assuming that they do not have grooves already.
I’ve always wanted to print a rock crawler. My neighbor has a nice RC one… and the guys on my street formed Placer County Rock Crawlers. So it’s a major culture thing in my neighborhood- they build them from scratch.
Some RCs have 4 wheel steering, which would be challenging. You need very strong servos for turning even when the full weight of the vehicle is on the tire. And most importantly: very low gearing. Totally possible, but that would be a fun one to do with cheap motors and printed parts. It’s probably well suited for a 3D printer. This design would have to be beefed up substantially though.

can someone help me with all this ? I can mail the files if you like.
@Christoph_Derycker what would you like help with? everything spitting, shelling, etc? Yah I can help. It would be easier if we do it on Fusion360 because then you can share the files or workspace easily with others.
with what email can i contact you on fusion ?
you can share your project just by posting the link to your file and then everyone can access it https://knowledge.autodesk.com/support/fusion-360/troubleshooting/caas/sfdcarticles/sfdcarticles/How-to-share-a-Fusion-360-design.html. you can contact me via b.turn2009@yahoo.com
you got invite ?
yah, I just got it.
So what do you need help on first?
need to get the different parts to print so i think stl ro slicing ?
Alright, cool. Have you ever used fusion360 before? I know they have resources for people who are use to Solidworks.

Well check it out real fast and see if the interfaces feels familiar and then I’ll start showing you what you need to do.
I kind of looked at the model and (unless I’m seeing something wrong) it seems like the skins aren’t made for manufacturing - too thin wall thickness, and there is quite a bit of detail on the small parts, struts. Unless the scale is huge, my printer would balk at printing this. Amy other thoughts?
Okay, I got a second to open the file. I couldn’t download it via the link you provided, but I was able to open it by going back to the original file on grabcad and downloading the .step files https://grabcad.com/library/rc-crawler-1-10-scale.
The parts are well detailed and even the rims are correct with grooves. You’ll have to check the thickness of the tires that you plan on using, but so far, breaking this up into printable sections will be easy. The only concern is that you may want to make modifications to the drivetrain. The designer even mentioned that his design for the powertrain was not sufficient. I think you should think about modifying it by using differentials in the front and rear.
i wil look for a other design for the drive train or do you have a example of hat you mean for the drive train ?
@Christoph_Derycker when I looked at the model I thought there wasn’t a differential in the front, but there is. So you could leave it as is, but look for places (if any) that you can see where you can improve the mechanics of the design.
