I know this isn’t a Fusion 360 forum, but I think this information will be very useful for people who use it and it probably works in other CAD programs as well. I needed to make a fillet between a component and one of it’s subcomponents, but because they weren’t the same component, they only made fillet’s with themselves, not between them. I searched around and couldn’t find a solution, but I thought of something that works very well.
Here is the sub-component I wanted to fillet to the main component:
Here is the component after the fillet:
It is quite useful within Fusion360 making the hook a sub-component so it can easily be duplicated and any updates will update all hooks. It is also useful within Bambu Studio because you can assign different properties to the hook to make it stronger or change the color.
Here is the process to make the fillet.
- Create a sketch on the portion (joint base) of the added component that attaches to the main component. I always make the added components a subcomponent of the main component I am attaching it to so it is contained within the main part when I import the .STEP into a slicer.
- Use the modify panel to create an offset of the joint base equal to the filletJointBaseValue you want plus 0.001mm. I also added two small lines on the right so the one part of the offset wouldn’t be included in the extrusion.
- Extrude the sketch you added with a value of .001mm.
- Create a fillet with filletJointBaseValue and it will look like your part is filleted into the main part. And for 3D printing it will be treated as a single object if you don’t separate the components.
Before:
After Extrusion:
After Fillet:
- If the added component already had a joint like in my case, it may just run the .001 extrusion of the fillet base into the main part and you won’t have to adjust anything. Otherwise, you might need to adjust the joint so that the fillet base is buried in the main component if you care about the extra .001mm.
Sounds useful as I have had this sort of trouble myself - but I am afraid I don’t quite understand how you are doing it (might be a bit too early for my brain to be fully in gear!),
Do you have any screenshots or diagrams?

Been a cpl years since I’ve used F360. Since employer finally gave in and allows Inventor to be installed at home that suits me now. Been working in the CAD field for over 20 yrs and know the difference between self-taught (like myself) and professional training which I’ve also taken. It’s usually recommended for programs like Inventor or SolidWorks to obtain training because it’s very easy for self-taught folks to pick up bad habits.
While what you found may work for now (no way to confirm or suggest anything else at the moment) just be prepared that it may break down the road if/when you work on or try to changed something beyond that feature in the CAD model. Not suggesting the 3D print will break, no idea what it looks like.
One thing that catches my eye but am not sure of (just got up and yeah it’s been a cpl years) is what you state in #1. About importing an apparent assembly into a single step file. There may be another way here if you consider combining your models/solids into a single entity (in order to create that single step file if I understand correctly) at some point before needing the fillet.
Again, while this may work now it may be problematic in the future if you attempt to modify the file afterwards.
A fillet was designed by the software manufacture to be on a single solid (I wonder if any solid modeling software allows fillets between two separate components?).
Coming up with a solution that gets by that “software requirement” may not be the best solution in the world, nor one that should be suggested on a public forum for this reason. Not saying it should be kept secret, suggesting that by suggesting a potential bad habit in a public forum will just spread the mis-information and not be ideal.
Post an example file for others to reference and/or provide a bit more detail. As mentioned it is a bit tricky/can be confusing to others, CAD software is not rocket science but it gets you there!
One tip I can give after seeing it hung up at a CAD support center is this, Just because you can, doesn’t mean you should.
I will post some screenshots later. Another method I saw is a Chamfer/fillet combination. What I proposed works well when joining inside corners, whereas what this person proposed is good for outside corners.
I am going to edit the original message with the screenshots.
I think my method is a pretty low risk method. Of course there are things I could change on the main component that could negatively affect the fillet. If that happens, I will either have to adjust it, or do it a different way.
I added this comment to my original message
I think the benefits both within Fusion 360 and Bambu Studio outweigh the potential risk of this approach. It is basically a part with its own built in fillet and wider base.
