I needed more of these. I tried some already on printable.com but I didn’t like the result, so I made one myself. You can see the black original that came with the original storage on the right, and the printed one on the left in white.

My settings for this print:

Draft: 0.2mm

Wall lines per unit: 5

Infill: Gyroid

Support: Normal, Everywhere, Line, 9%

Print 1 line of skirt.

It takes about 45 minutes to print one cube corner with my printer.
