Headphone holder, desk clamp

I got my inspiration for this particular headphone holder from many designs, printables asks if this is a remix, it is not. I did the design on this although it may look similar to others. Anyway, what makes this different from others, 1 is the screw mechanism, it's larger gives you more area to grip it. Second is the direction of the cable management on this, it's underneath the actual headphone holder, but it opens outward making it easier to wrap a few layers of cable under it. 

I've tried taking into consideration the differences in mounting surfaces so I've included 2 different screw sizes, for desks that are a little thicker the shorter screw should work, my desk uses thinner wood, so I had to use a little longer screw, so I've made both an Inch and an inch and a half. Also, when using the screw there is the stopper, which also needs to be factored in when determining which screw that you use.
