/diy/ - Do It Yourself

Does anybody have tips for printing parts that have really small holes in them? Pic related, units are inches.

My printer is a Qidi x-pro for reference. It seems to consistently have issues with first layer bed adhesion when it prints the wall for the tiny hole. It's like it just doesn't even start to adhere to the build plate at all.

I've identified 3 main types of failure modes for bed adhesion that I see a lot, and tiny holes involve 2 of them.
The first one I see is often seen in long, straight or mostly straight lines. At first it looks like it sticks to the plate just fine but very quickly the beginning gets peeled up as the nozzle moves away, I think this is because of a little string stuck to the side of the nozzle that is connected to the first line and peels it up. (This isn't the issue I have here but would love to get advice on this because Its super frustrating)
The second failure mode is with very tiny features printed onto the build plate, regardless of if they are straight or curved. I think what is happening is that the adhesion of the molten plastic still in the nozzle is stronger than the adhesion to the build plate since it has so little surface area.

The third failure mode is seen specifically with curves on the first layer. I notice that curves with a small radius tend to not adhere much more often than a curve with a large radius. So I could have a long straight line with great adhesion and then have a sharp 90 degree angle or a really tight curve and it peels up at that spot, but if I make the curve larger and more gradual it generally works much better. When possible I try to design parts with that in mind, like external corners. But in the case of pic related part (which will have a screw threaded into it that MUST be that size and can't be made larger) I can't really do anything on the design side of things.

>TLDR: I cant get small circles to adhere to the bed, advice please?
