I own a Seaga VC6000 victory snack machine, that I operate at my place of employment. It’s been a very reliable machine, but it will only dispense thin items like KitKat‘s and Hershey bars. I wanted to vend something thicker like a cupcake or mini donuts, so I developed this 3-D printed spiral replacement. Since it’s installation, I have had zero problems dispensing thicker items.

Printed in two sections, then glued together, the back spiral contains a cut out for a carbon steel linchpin that is 3/16 in diameter with a 1 1/4 inch usable length, o1 5/8 long, and is attached with screws and washers to hold it in place. This is what allows the connection, from the motor to the newly printed 3-D spiral

Because my slicer did not support rafts or supports, the STL files have both built in. If this is a problem for you, please use the original 123D file(s) to create new STLs to your liking
