This Apple container  comes in two variations.  The first one has a lid that simply slides into the base, this is the no lock version.  The second one has a lid that can twist to lock into the base. Labeled on the build plate as the twist lock. 

A stem and leaf are printed separately to insert into the top half of the Apple. I typically print these separately in different colors.  Depending on the scale that you make the Apple some gluing might be required. The original size of the Apple is the smaller version and the stem and leaf both snugly fit in the top of the Apple when pressed in.  The larger scale, 200%, will have a leaf and stem that will have more wiggle room and might require some adhesive to stay in place. 

A small worm hole in the Apple gently curves through the top section. 

This makes for a fun classroom toy, since that was the original purpose of this design. I printed them for each student with their name on the top section of the Apple.
