Slicer infill learning/sharing

Hi I didn´t know where to put this but I wanted to share my experience about infill %.
The only different is infill %.

On the top it is 100% and don´t fit together not even with “allot” of force.

On the bottom it is 50% and fit snuggle together.
Feel free to share your experience.

100% infill is known to deliver too much filament. It’s recommended to stay under 60% (for various reasons already commented elsewhere).
