I am 3d printing a magazine like to hold batteries and i wanted to make two, one with White color for the AAA batteries and the black one for AA ones, but when i changed the filament to the White one it started to do this like strange things inside, any idea of how to remove them or how to Avoid them to happen.

The settings on the black one where: 100% infill, 80% speed, 215 Degrees Celsius in the nozzle and 70 degrees Celsius in the bed.

The settings on the White one where: 30% infill, 80% speed, 230 Degrees Celsius in the nozzle and 90 degrees Celsius in the bed

The 3d printer is an anycubic megaS

And the filament I'm using is PETG, both colors from the same brand.
