Mostly Printed CNC Z-Carriage Mod for Full router

Updated v6! Final and Ready!
Part no longer supported. All file are final and no edits can be made on my part.
This is a two part mount for a 300w Sunwin spindle(http://www.amazon.com/gp/product/B00CLNSMC2/ref=oh_aui_detailpage_o07_s02?ie=UTF8&psc=1). Note that my printer prints slightly over bigger on outer diameters and smaller on inner diameters so the mounting brackets fit perfectly on the spindle. I have also uploaded the STEP files for you to edit if need be(these are exports from .ipt (Autodesk Inventor) so feel free to comment for any changes that need to be made).
