The handle holds the patches down while you rip them. The spool adapter fits in the roll of patches and then the rod goes through it. When the handle and the end piece are lined up correctly, three patches should fit perfectly. This is a feature that can be easily adjusted to fit a different number of patches. The feed tracks keep the patches held down as they travel through the device. The feed track 1 has a slight slope under it and the feed track 2 does not.

SourceAmerica Design Challenge
These files were created a project for the SourceAmerica Design Challenge. We created a device that will tear "Type B" patches into sections of 3. These files can be edited to tear all sizes of patches.
