I thought it would be fun to make a kind of dwarf\strongbox\dungeon themed egg for the egg hunt next week. Its hollow. There is a little detent that helps hold the halves together, so it doesn't just fall apart. I made it to be the same size as a regular egg, but you can scale it up if you like. When removing the supports use the end of a spoon to remove any leftover strings that may interfere with the edges coming together cleanly. For the black and red one I just colored the lines with a permanent marker rather than do 10 gazzillion color changes. If you print one in color I would love to see it!
