This is a 2-part sandal for kids that can be printed on a Cupcake. This is a very simple & easy sandal that was designed to fit a ~5 year old (ie, ~kids size 12). Because at the time I only had access to Cupcake, it is designed in two parts that are joined together using acetone. Print the top and bottom halves, and smooth the joint edges with a small flat file until the pieces fit snugly together. Weld them together by putting the pieces together so they are flush, dribbling a small amount of acetone along the joint on both sides, and then squishing the pieces together. Hold firmly for a minute or so and then let dry on something flat (eg. glass or wax paper on a flat board.)To print the other foot, just mirror the parts in ReplicatorG or your printer program. Strap material is 9/16" webbing. A nail is used to hold the strap in at the toe, and the sides and nail are hot-glued down. I also used hot glue in the channels on the bottom to provide a little grip, but other rubbery substances that will stick to your print material could also work.To see detailed instructions and images on how to assemble the pieces as well as instructions on how to design your own custom-fit sandals, see the Instructable here: http://www.instructables.com/id/How-to-make-3D-printed-sandals/
