Nắp chụp tâm mâm 57mm (BMW + ...)

I feel resigned to the occasional theft of the rim caps. Perhaps a cheap 3D print will not be attractive to thieves?
FreeCAD model included - feel free to customize it. The design is intended for MMU/AMS printing, but you can easily separate the colored front part from the mechanical part.
This is a quick afternoon project, it will be nice if someone takes care of the details (silver borders, letters B M W, etc.)
Of course, the design can be used for other brands, or you can leave a blank space instead of the logo - simply as protection for the hub.
