Irken Invader Logo from the cartoon Invader Zim turned into a pin. About 4.5in x 2.5in
Print out 1 of each part. You will need some small brass nails and some lapel pin holders. You will also need some super glue, epoxy, or plastic weld to joing the parts together. I tried to provide pictures of how it assembles. It is pretty simple to assemble. I had mine done in about 15 minutes. As a note, the nails I had to cut down so the pin holders would fit.
I Printed mine at .2mm layer height with 3 perimeters. And enough top and bottoms to make it solid. As the part is very thin and I figure it would take a lot of abuse.
