Sorry, files were not uploaded on above post because they exceeded maximum upload size on the posts. I sent an email to you directly. We will see if we can increase the upload size here.
Thanks for being so helpful! I'm currently trying to learn how to use the AtlasViewer software, and so I'm not sure if my probe.SD file would 3D-print well. I really apologize for the delay in my response.
I've attached my probe.SD file ("probe-rev1.SD"), in case it's possible to convert it to an .STL. If it's printable, I'll follow up on this with the finished print!
Edit: 'probe-rev1.SD' is available here.
