Kingroon Spool Holder

This is my updated version of the my remixed Kingroon spool holder and filament guide https://www.thingiverse.com/thing:3969208 (which is a remix of a few other pieces). My original design had multiple flaws, but the biggest was the small 20x40 rail insert pins were not strong enough to keep the filament weight from snapping them off in the guide. So I figured I'd change the center of gravity and put the filament directly above the vertical rail. This way the pins no longer are needed for their strength but more for placement. I also shortened the spool arm to try and keep the spool from moving around as much. There are two files, one you can print with the Kingroon, but requires a two piece arm. The other is if you have access to a larger print bed you can keep it to one piece arm. Since this is made for the Kingroon I've printed it as if that's all you have.
