Used a Bambu A1 mini with overture pla pro 

Print at 105 % scale

Fits on 2 Plates for A1 mini. 

Used fuzzy skin setting 

fuzzy skin: Contour

fuzzy skin point distance :0.3mm

fuzzy skin thickness: 0.3mm

I used tree supports and came off easy.

Some sanding was necessary for the fillets to make everything line up. It was like 3 minutes of sanding. Perhaps you will not need to sand without a fuzzy skin setting, but I have not tested this yet. 

This model fits a 3x3x2 inch sticky notes inside with room left over.
