HELP. Find or 3D print my favorite fin

Tried searching on-line, but to no avail. I lost 2 of 3 of my most favorite box center fin. So I was hoping to get it 3D printed so that I can keep the last original one in reserve. Any one know how ?
If not, the "Wing fin" was made in Australia. So if any one can find some, I'll buy them. I had them in Black and Blue, but any color is no problem. I do have the FCS 3D center fin that's very similar, but they're brittle and fall out of the adapter.
