About this 3D model

This is a replacement knob for the Weller WES51 Analog Soldering Station. I designed this part after being given a WES51 with a broken knob. WARNING: I have verified that the base of this part will print, but have not yet tested it on my soldering station. There is a good chance the rectangular shaft is too thick, as I would like it to press-fit into the potentiometer on the soldering station. NOTE: SLDPRT is SolidWorks 2011 format.
