Sausage Sizzle Insert

This is an insert for the charming push your luck dice game Sausage Sizzle.  It's a very simple game but having each player's token set separated helps with setup.  It's my first model so I would appreciate any constructive criticism.  There is a “non-manifold edges” warning that you can ignore when printing.  I'm still trying to figure out what that means and whether it's worth fixing.
