Simplified Flavor's shell design slightly to allow both the top and bottom of the shell to lay flat on the print bed. Less over hangs to deal with. Also note a new thumb notch was added to the lid to help with removing the cart from a NGPC system.
NOTE - Suggest adding printing support for the Base STL file. The Lid STL has support added directly to the model on one side. There's just a 0.2mm gap to help with removal.
