Canadian Maple Leaf pendant or earring

Canadian Maple Leaf with cavity for incorporating wire to use as jewelry.

The leaf is split into bottom and top sections.  Print the bottom part, insert your eye pin or other hanging hardware, then print the top layer. Remember to centre both in your slicer before slicing so the top is printed properly on the bottom section.  You will have to set an appropriate Z offset for the top section, 2.0 mm, to ensure it prints on the bottom section.

I recommend ironing the top layer of the top section.

You could merge the two sections into one component and insert a print pause to allow time to insert the hanger.  I find it easier to use two pieces.

The cavity may seem overengineered.  I have it stored as a standard design element so I can add it to anything that might need to be hung, like Christmas ornament (on a thread) or jewelry or wine charms (on wires).  Bend the eye pin or wire to loop around the internal structure to add some security against the hanger pulling out of the object.  Or use a loop of thread and hook it around the internal circle and then out the top.
