This is a spacer to extend the flyer rods on the EEW Mini by 3.5mm, making it easier to wind the bobbin more fully.
You'll need to remove the flyer rods with a screwdriver, then reinstall it with the spacers between the rods and the flyer disc. It's a bit of a chore, but once they're installed, you don't need to remove them.
You'll need to print two copies for a full set of spacers.

The infill is high because of the installation position of this part - it can get squished. I used 2 perimeters, and 3 top/bottom layers on mine.
