Wall Mount Extension for Modular Wire Spool Holder

My remix simply extends the Spool Holder to allow wall mounting.

I had an issue with importing the original STL File into SketchUp as it showed there were no flat surfaces. I corrected this however when I added the extension an error appeared, which I couldn't fully remove.

There was no apparent issue in my Slicer (ideaMaker) so I printed it, which came out fine.

Hopefully someone will be able to make use of this remix.
