M3d Pro side mount large spool plus guide

I wanted a side mount spool holder for my pro, Found this one but it was too small for my big 3rd party spools, so I modified it.

I created 2 sizes of shaft to accommodate 3in wide or 4in wide spools, you should be able to use the original shaft as well if those 2 are too long. I added structural support for the extra weight and extended the arms out to 5.5in
