My first Blender model without a tutorial! I got Blender the other day and this is the first thing I've made by myself. I will be creating a flexi model of this soon( once I figure out how to;) ).

Doesn't Matter

Yes

I would put a little bit of the model under the grid workspace in Cura so that it stands and is easier for your printer. I would have done it myself, but when I tried in Blender it seemed hollow or something, so I left it.
