There are alot of Porsche Crest STL's on the web for printing, but I didn't really care for what was available in the public domain. I downloaded one of the better ones to use as a reference, but it had alot of errors in line width, font, etc…errors in the horse, etc, and was super faceted.  So I drew a new crest from scratch using splines, etc, and added some techy style to the textural elements.  I happen to be a Porsche owner, so I got a nice high-res image of the crest on my car's hood to help as for accuracy.

I added a frame/border, and it has an integrated screw key-hole for hanging.  The model is almost 10" Long, but does fit on the bed of my Bambu X1C and printed perfectly without issues.  The 3mf file has all my settings, but I also included the step file that was saved from an assembly, with separate parts designated for the colors.  So no painting is required in the slicer, and the color is depth controlled as objects.  I also included the source Solidworks part and Assembly files if you want to make a remix.  I have about 5-ish hours into this model, so please don't start selling these on Etsy.

I printed this with an AMS, with Red, Black and Gold PLA.  0.4mm nozzle, 0.2mm layer height, with 3 bottom and top surface layers, 15% fill.  I am happy with the result, it printed in ~ 6hrs.
