I own a Seaga VC6000 victory snack machine, that I operate at my place of employment. One of the things I was having problems vending were small Slim Jim’s, as the patrons would shake them out of the machine. I designed in 3-D printed a guide rail, that holds them upright, and prevents them from falling down at the end of the spiral
You will need to print out two middle sections, and one front section. Sand off any excess on the stud, and clamp and glue all three pieces together. Once assembled, the rail extends approximately 13 1/2 inches. And can be drilled to the side of the existing sheet-metal guide, or secured with glue or double sided tape
I’ve affectionately entitled this project the "eat me rail" in homage to the late 90s Slim Jim commercials

This design, as well as previous designs, was done in Autodesk’s free 123D design. This is now an abandoned piece of software, that I am still very proficient in. You can download its last revision for Windows (2.2.14) here, but understand that the online cloud storage option no longer works.
The .123dx file may contain sketches, solids, or both needed to render the final STL. and is included to ease part modification for your purpose.
