It's a little knob, I need to print it upside-down, but the details (petals?) in the knob looks terrible since the printer tries to fill in the holes instead of printing over them. If you look at the thing you'll know what I mean.
I solved it by printing the knob and the "distance between knob and drawer" separately and glued them together instead, but would still be nice to know if there's a way to tell the printer to not print in the air but to anchor the sides first.

Here's a pic of the principle I want to achieve. Left is how it is now, and right is how I want it to print.
