A very small part with supports needed maybe?
Hello,
I'm trying to print this small piece with a outer diameter of about 10 mm: https://imgur.com/ZAES1y9
As you can see here, when I turn it upside down, there is a small part with overhang that of course wont print properly. If I don't turn it upside down, there is also overhang on the "dome" part very close to the bottom.
I am cutting what is too much off. How would you do this, generate supports, add them manually?
Thanks for reading
RE: A very small part with supports needed maybe?
In the picture of the model turned upside down, what happened to the side walls?? Just looking at the main picture in your post, I'd figure printing upside down should bridge just fine. Printing in the original position may be okay if the overhang at the bottom is a chamfer, not a fillet but at that size even a fillet may come out okay. But hard to gauge without seeing the STL directly.

The side walls are no actually part of the final thing. I just need it so it prints fine (upside down).
I attached the stl file. When it's sliced as it is, there are some layers that have overhang. Doesn't that mean it will not print correctly? I'm fairly new still.

I don't see the STL!
you need to zip compress the file, and then attach the zip file to the post
Does the dome side, need to be domed? if it had a chamfer around the outside it would print with the gear up...
maybe you could print a washer if you needed to create space for the large diameter section in the final model

So what we're seeing in the picture is actually two parts, an outside ring and an inside wheel? I'd try to print it right side up. If you have control over the design, as I said before and also suggested by Joan, use a chamfer instead of a fillet.
if you need to print it upside down, I'd use paint on supports. Actually, I'd decide a ring just like the one that is apparent part of the final assembly but make it 0.2 mm shorter than the height of the central part and use it as a sacrificial break-away support so that the slicer can bridge the overhang.

RE:
You can also combine what Joan and fuchsr described: A fake-fillet. #3DSenpai
Like having a >= 45° chamfer on the bottom vertical part (in upside-down orientation) and
then using a fillet on the upper edge of the chamfer, to round the chamfer towards the vertical wall.
Then you can print it upside-down, as described.

Sorry I just forgot to add the STL. You are right, it doesn't need to be domed. I went with the chamfer at an 60% angle.

No, it's just one part. I had the ring there as a support, which I later cut off. Didn't look that good to be honest.
Here are some pictures of the new version:

Looks good. Chamfers are usually the right answer unless you need the rounded surface for a particular fit.
