To keep cotton pads nice and tidy and always ready to go! The dimensions are specific to the cotton pads from DM (Babylove, home brand). They may, however, fit for other cotton pad brands too.
We use it for our daughter's changing table, which has drawers in which we used to store the cotton pads loosely without anything that would keep them tidy. Now they can stay in place and be piled up high for maximum efficiency, because - lets face it - changing table drawers can get very cluttered.
I printed the holder in SUNLU white matte PLA with 5% infill, 2 perimeters, 1 bottom/top layer. I have provied a version with cutouts for less material use but haven't printed that version. It may need support at the top arch of the ellipses.
Enjoy!
