Expanding Egg Fidget

My kids love playing with these fidget eggs I designed. These print in 2 pieces: a top of egg that contains the fidget mechanism and bottom that has groove to connect top to it. There is both a flat bottom if you want them to stand up or a round if you want it to look like a real egg. The tolerance on the bottom can vary depending on filament expansion which can vary even with color. It is best to start with the 0.1 mm tolerance print first and see if works and then try 0.5 mm followed by none. On some prints, it fits in snug and no need to glue but on others just needs a dab of glue in groove or on edge of outer ring to attach solidly. Default you can just use 0.1 mm and always glue. Size wise - default size is good for kid size hands and 125% is slightly bigger than a grocery store egg.
