Grease Cartridge Cap System Reiner

This is a cap for grease cartridges with a “System Reiner” connection, which features a conical tip and a non-standard thread. These cartridges are quite common, at least here in Germany, but when I lost the original cap, I found it surprisingly difficult to locate a suitable replacement, so I fired up CAD and created this neat little solution.

I’ve included the F360 file as well as the Step so you can tweak the design to fit your specific needs, especially as the threads are quite tight and may need adjustment based on your printer’s tolerances, filament choice etc.

If you give this cap a try, don’t forget to share your makes! I’d love to hear how it worked for you and if you encounter any problems, feel free to drop me a message.
