I really liked the original by Camco [https://www.thingiverse.com/thing:1660254], but my Fusion 360 skills don't yet include erasing text...
WHY?!?
Well, because I use Cura as my slicer, and the default layer heights didn't jive...
So I kind of had to design mine from the ground up, using theirs as inspiration.... either way, I wanted to give Camco a shout out, because their design rocks, and you should all check it out, then come back and laugh at mine some... ;) haha
Either way, it displays the cute little frogs [https://www.thingiverse.com/thing:80870] Perfectly!
If I plunge into Multi-Material printers, I will update this so the text can be set to a different extruder.
