Bottle rinser (for homebrewing etc)

Simple Bottle Rinsing System for Cleaning Before Bottling. This design allows for easy cleaning of bottles before bottling by using a compressive spring or an extending spring that can be easily sourced. For those hard-to-find springs, this system can also utilize rubber bands as a substitute. The springs used are approximately 40mm in length. Important Printing Notes: When printing the "Grill" part, note that the thread tolerances may require some adjustments. I've found that adjusting the horizontal tolerance to -0.5mm allows for easy screwing and minimal strain on the threads. As a result, tolerances can be relatively loose. Sharing this design is free for fellow homebrewers, but please contact me if you plan to use these files commercially.
