Simple telescope eyepiece tube to FE/E-mount adapter that allows a Sony camera to use a Meade telescope as a lens.Print this upside-down (flip the STL object so the thin tube portion is printed first) and have your slicer add a little brim to keep it secure during printing. I used PLA at 0.25mm with 2 shells and 40% fill. The "MEADE FE/E" label text doesn't print very readably... oh well. Tough to print small text on the underside of a 45-degree slope. Even after filling the letter indentations with white paint it's not pretty, but the text does label it and tells you which side is up. The adapter works nicely. It was not a very clear night, but the moon was shot straightforwardly using this adapter to put my NEX-5 on a Meade 1250mm f/13.8.
