Mark 3 spool holder arms for 2020 VSlot alumimum extrusions

As requested by another user, I've modified my own design to fit onto a 2020 VSlot aluminum extrusion.

I haven't printed these arms myself yet. Therefore, this design must be considered a “work in progress.” Please feel free to provide my feedback if this really fits a 2020 extrusion well or if I have to rework it. And please provide some pictures of your print to that I can understand issues with the current design better.

Thank you, and happy printing!

P.S.: Please read the instructions and information on the original design page.
