I didn’t like cutting up my PVS-14 eyepieces so I 3d printed the lens cell for the eyepiece and used the lenses from a Plossl 25 mm telescope eyepiece. And 3d printed a sleeve to go around the lenses to make fit snug. Its not perfect, but good enuff. If it turnes out I use this housing often I might go all the way and use PVS-14 eyepieces.
