Summary

"Functional and unique gear bow tie! This is the only true bow tie for mechanical engineers!

It is easy to print and assemble, no glue required. Parts are designed to be press fit together. Only add any tying ribbon you have laying around. This thing was entirely designed using SolidWorks."
