About this 3D model

Got an old Mackie mixer to use as part of a video job. Of course it was missing a volume slider for one of the channels. Here is the replacement I created built from dimensions taken from one of the original sliders. **UPDATE** **Check out the volume knob I just made for the same mixer** http://www.thingiverse.com/thing:75806 **After review of the printed piece I will probably go back and change it up a bit. This one works well but it isn't close enough to the originals for my liking.**
