Skyzone Fan Mount Mod

This is a mod of oldhui's Skyzone fan mount mod that incorporates a 30mm fan (vs his 25mm). Ideally, one would get the original cad files from him and redraw for 30mm, but I was in a hurry and slapped the STL into Fusion360 and drew up an adapter ring, then glued them together and spat out a new STL with them combined. (Learned some new tricks :) ).
