Vivitar TX rear lens cap (short version)

thingiverse

Rear Lens Cap for Vivitar/Soligor Interchangeable-Mount Lenses For Use When Mount Is Not Fitted on Camera. This Version is Designed for Telephoto Lenses Without Protruding Rear Elements. It Works with Vivitar TX and T4, as well as Soligor T4 Lenses. This is a Modified Two-Piece Design, Improved from the Original One-Piece Model. The one-piece version tended to Wobble on Flat Surfaces If the Base of the Lens Cap Wasn't Perfectly Level. To Improve Stability, the Smaller Piece Fits Inside and Must Be Glued in Place. The Larger Piece then Forms a Central Recess in the Base, Allowing it to Sit Steadily on Any Surface.
