Moved Fusion360-specific stuff to its own file, because I’m not using this for threads anymore.

Thread scaling in Fusion360

When I create M6 threads in Fusion360, the only scaling factor available is 100%, which prints too tight, so here is a somewhat-janky workaround:

• Search %localappdata%\Autodesk for the ISOMetricprofile.xml file. See this article for details.

• Find this section:

  <ThreadSize>
    <Size>6.0</Size>
    <Designation>
      <ThreadDesignation>M6x1</ThreadDesignation>
      <CTD>M6x1</CTD>
      <Pitch>1.0</Pitch>
      ...
      <Thread>
        <Gender>internal</Gender>
        <Class>6H</Class>
        <MajorDia>6.147</MajorDia>
        <PitchDia>5.425</PitchDia>
        <MinorDia>5.035</MinorDia>
        <TapDrill>5.0</TapDrill>
      </Thread>

• Insert these scaled alternatives:
