<p>I already tried a lot settings in Cura and try to search for a solution but without success. Maybe someone got this issue and solved it.</p>
<p>I want to prevent Cura from printing such gaps at the wings to make it in one run. With ironing one run would (hopefully) bring better results. See the animation for what I mean.</p>

Print it as a whole object
Use 20% infill.
Profit!
