converting a*.dxf file to a *.stl 3d file and print

I use these drawer guides in a lot of furniture I built years ago , and I had a supply which did not last they all pretty well disintegrated over a long period of time, and amazon was asking 19.99 each , so using logic trace I will create a *.dxf file and then convert it to a *.stl file format and 3d print this drawer guide, the tracing will save me a bunch design hours
