The Oberving Program Division is pleased to announce a new feature on the Astronomical League website:  A repository of helpful 3-D Printer Files (STL Files).  If you have a 3-D printer available some of these aids might be hepful to you in your observations as well as soutreach activities.  They are located on this web page:  https://www.astroleague.org/navigating-the-night-sky-guides/

If you have printed additional tools on your 3-D printer, please send them to Aaron Clevenson at aaron@clevenson.org for inclusion.  Criteria are simple:

1. You have to have printed the for your use.
2. They have to be useful to other observers (not “one-ofs”).
3. Ideally, they should not require supports to print.  A brim is not an issue.

Thanks.  We look forward to seeing your tools.
