MK7 Hack to Enable Filament Changes Mid-Print

Credit for the Mk7 stepstruder design goes to Hoeken and nycdesigner; this hack is based on their work. The modification involves using a 5.15mm hole instead of dremeling it out, requiring no extra effort. Although I haven't tested my version yet, the files are derived from Hoeken's solidworks file.
