Ok. So here is the deal.
I went ahead and I decided to 3D print my first build.
Cessna 172 by Xavier
Which, while being a rather irregular surface to print was more or less considered the norm among airplanes.
After all, the landing gears are non-retractable. Those retractable ones are more of a issue.

The point is, I am here to complain about that square (SQUARE) created around the "normal" landing gear". It also defy physics in places like my rear landing gear by not adding support (which, if you want to blame me, is acceptable for me.)

I have no idea how does it mess with overlapped parts.

This all look like a detailing issue, right?
Well let me tell you, that the size of the build.
The width, of the entire 3D model (unscaled), is 15mm.
The height is more or less 13mm.
The length is like 14mm.
If SimplePlanes generate a 1000% scaled file, there are a lot of room for compromises. Joints can be enhanced by placing triangles that link them, the place where overlapped parts exist are removed and among other improvements.
The freaking box in the wheel will also be able to be deleted (because how the wheel, no matter the orientation, is able to be printed without the need for a large amount of support

The propeller remains a issue, but can be set aside to print separately.
