ICE Whistle, Portland Frog, "Don't Obey" and Resist Emergency Protest Whistle

I'm not sure how it was colored.  I ended up making different groups for each color, then imported all the STLs at once (I use Sketchup, which loathes little objects, so I scaled it up 100x, and then scaled to 1% after importing).  That made it easy to color.

There's a main “Protest Whistle.3mf”, but it has Bambu X1C info, so may not work for other software.  Also Protest Whistle.stl, but that may lose the info needed to color it.

I imagine most systems should be able to import all the STLs as parts for a single object.  Scale them to 1% to fit.  (The whistles should be 22mm x 43mm x 4.6mm).

I had to tweak the process for the top details, so it was convenient they were different objects.  I made finer lines on the “DON'T” frame because it wanted to miss the bottom of the N.  And I tried that on the frog outline as well.
