Root 3 CNC Control Cable Strain Relief Assembly

This thing is a strain relief assembly for a Root 3 CNC control cable. It is designed for an 80mm spindle. This is my first attempt at using Fusion 360 for a multipart design, so mileage may vary if you attempt to modify the base files (I'm sure I managed to do something the wrong way, although it printed just fine for me). I used M3 screws to bolt the 3 components together. There are also 2 screw holes in the bottom of the wiring tower -- I glued 2 50mm M3 screws in those bores to attempt to give the tower some added strength...
