STL Celtic Cross

I have some titanium I would like to try and do a small Celtic Cross
or other Celtic Weave design.
Would one of you artistic types out there be willing to email me a
.stl of the above mentioned art?
I can scale it and modify it, I just can't create it.

Also, any reccomendations on how to work with Titanium? this is a
scrap peice from a connecting rod blank. It is the very expensive and
hard stuff. It also has an oxide layer from the wire edm. I
understand I need to dissolve this layer with acid or something?
Feeds, speeds, coolant, tool reccomendations?

Thanks!
