I drew this mostly using splines off of some stock images for a little gimmick, hope someone else can use it too! I've included a version all as one piece and a version with separate models for dual extruder setups. I forgot to save the file as a solid piece on the non cog versiont when i was making it, but it's really easy to merge files in cura or slic3r (just select both models and right click the option: "merge models." Really don't need any infill and it pprints well at most layer heights, the images are printed at .15mm and .2mm If you want to decrease the size, it gets tricky below 50% and you lose a lot of detail but still pretty recognizable.
