NC Near Space

One of Splatspace’s contacts in the Durham Public Schools recently reached out to us for help with a personal project. He has been rebuilding vintage Geiger counters, and a “Prospectometer” he had acquired had a broken meter indicator.
He found a replacement meter that was compatible, but it was circular instead of the “D” shape of the original.
It was fast work in FreeCAD to create a new mounting ring to mate the new meter to the old Geiger counter case. We printed it in black ABS on our Lulzbot Mini; a little acetone-vapor glazing and sanding for an appropriate finish, and it was done.
This is a great example of how open-source design tools simplify the process of “Manufacturing For A Market of One.”
