@JenMsft I'm quite tempted to 3D print something like this.
@PCOWandre @JenMsft Please share the files when you do! I want one too!
@jbiserkov @JenMsft Something like this?
@PCOWandre @JenMsft Great start! Can the "Loading..." be gaps inside the material? Also maybe the middle section can go a bit closer to the viewer? - to prevent tipping over and exaggerate the 3-dimensionality? Just my 2 cents, I've never printed anything.

@jbiserkov @JenMsft The text is cut in to make it easy to print (no bridges, no tough overhangs) and easy to colour up in the slicer for multi-material prints.

Anyway, here's the link to the file: https://www.printables.com/model/559301-loading-demo

If you'd like the .f3d source to play with, let me know and I'll export it.
