Hello, I am sharing my own idea of box, which suits Ikea Mickey drawer.

Size 10 cm x 10 cm (7 cm in height). / ~4 inch x 4 inch (2,75 inch in height).

Printed with 0.2 layer and supports. 

I set 0.1 support material distance, but you can try with 0.2 (it will be easier to remove supports). Snug support style.
