Trouble in designing and 3d print a fixed-wing drone wing

[m_alzurghni123]

Hello everyone, I'm facing some trouble with my fixed wing drone internal wing rib structure

So, I have followed the steps of this  video https://youtu.be/QJjhMan6T_E?si=0Bmh6c-Hv2hbTvNv

My attempt to make the structure in this video ended up with the following result 

 as you can see it looks fine but after combining with cut the internal ribs with the wing some ribs pentrate the wing body creating gaps like this 

When trying to print it using something like vase mode in the creality slicer called `spiralize outer contour` these gaps is created which makes the print goes completely destroyed and some edges snaps if I try to apply little pressure on them so what do you think the problem is and how to solve it BTW here is the sketch of the ribs pattern

the f3d file is attached

Can you File>Export your *.f3d file to your local drive and then Attach it here to a Reply?

If it is not stable enough, you have under-extrusion or poor layer adhesion.
To increase layer adhesion increase temperature.
May also depend on the material.

BTW, you have to design the elevons first.

So it supposed to have gaps?

No, there must be no gaps.
The walls of the gaps must melt together.
Seams remain visible.

There must be no gaps in the design itself or after printing it?
