Battery Fifo for AA Batteries

thingiverse

I thought it's good to have a bit larger Battery container, that allows to identify, how old the batteries are (or take the oldest out first). I wanted to learn how Sketch Entry for forms work in FreeCad This is not yet printed, I thought of Printing in PLA, maybe I need ABS. It's ca. 75g material. Maybe the walls are too thin, I included the FreeCad file. To make thicker walls, change the "Value" in Left->Links->Cut001->Common->Cut->Offset. Currently it's 0.8mm + tolerance that enables Cura to slice (0.81mm) Print Left and Right side and stick them together. Please report a make.
