Finger shark, one block

**This is a remix of [zheng3's finger shark](https://www.thingiverse.com/thing:432223).**

Instead of having the head on the finger's end + a ring with the fin, I've remixed it to have a single part on the finger: I think it will be better for kids, with a lower chance to loose or swallow the ring / fin ;-)

*Note: I've included a version with "supports", but it's done quickly and is not supposed to be perfect, simply to help the piece to stay on the bed. If you want a perfect result, check your slicer settings and use internal support if required.*

**Edit:** I've added a second version "with more supports", because I tried it on a printer and it was not enough to stay on the bed, so this one should be preferred (or not, if you use your own supports). I used it to print, without supports in the slicer and it was just fine.
