I wanted a nice cut-out design on the rewinder spool holders I was working on and used the two-tailed lion from the Czech coat of arms as a template.  It turned out well enough that I thought people might enjoy the STLs as separate parts. 

Included are 5 files:

• CZLion - a 3MF containing all the shapes below as parts
• CZLionSingleRaised STL - a single STL combining the backing and pieces to make a nice plate, works great with filament change after the backing plate height
• CZLionMMOutline STL -  the outlines of the pieces which can be used as a multi-material modifier to include this design in your prints
• CZLionPcs 3MF - the inner parts which can be used as a multi-material modifier or used to subtract the shape from models (3MF because STL does not like separate pieces).
• CZLionMMBacking STL - the larger backplate/baseplate, probably best used with the inside pieces

Enjoy
