Parameterized Socket Rail

I love these [TEKTON socket organizers](https://www.amazon.com/dp/B008TM15LE/ref=cm_sw_su_dp) (the red one in the picture), but unfortunately they only come in two sizes: large and huge. So I made my own rails that work with their clips for some of my smaller socket sets. The length is parameterized, so you can make one as long or as short as you'd like.

You'll need the [clips](https://www.amazon.com/dp/B008TM15LE/ref=cm_sw_su_dp) from a TEKTON rail as I haven't tackled designing my own clips - they're a twist-lock design that works really good so far.

I've printed this in both HIPs and PLA on a Lulzbot Mini. The fit is a bit tight, but it keeps the clips from sliding around since the teeth are too small to really print for me (I should tweak those variables and re-upload...).

The STL is for a version that is 164mm long in total (140mm rail + 24mm hanger).
