A difficult subtraction in Part Design

[kisolre]

Here are both fanducts. Not mine design, just downloaded from Thingiverse
Notice the nail polish covered ends of the old one. It worked like that quite some time. Fillament seemed expensive at the begining

We are getting quite offtopic here but...

Yes, we are... but we are sorry

Yes. This way the exit will point up and if the angle is more than 40-45 deg it should print ok without any supports. I made an single body (no treasure there )model of your duct:

Thanks a lot! I have already guessed it I was printing a new duct when I read your message

Notice that at the first bridge layer it might fail because the slicer tries to connect bridge to bridge:

I had something like this... but all holes were already closed at the 6th layer (height is 0.2 mm, bottom/top are 1 mm).

So before printing allways check your generated g-code and if you think that it might fail somewhere think what to modify in the model/slicer settings/supports included in model,... to fix it before printing.

Ok, thanks.

It is russian, but there are many photos and Cura English screens.

What is this?

I have some error messages:

Where do you get those errors?

[koluna]

When I open your file.
Those errors are in Report View.

[kisolre]

Are those errors (red) or warnings (yellow)? Nothing shows here with:

Are you sure those are from that file? RMB on report view/Clear to remove all messages. Open the file. Do you stil get them? Nothing fancy in those moddels to show such errors.

Can you retry with a current 0.19? I think there has been some work concerning these extensions.
