After sampling a few other chainsaw mounts I drew this one up to make some improvements.  I wanted it to attach right into a stud and not drrywall anchors, so the fasteners are oriented vertically.  Removed a few stress risers / weak spots on others I tested (who doesn't like things overdesigned).  Some mounts I tried were phyiscally larger than necessary.

Holds any rear handle Husqvarna saw (tested 550xp, 562xp, 576xp).  Share in the comments if it also works with your saw!

Printed with Bambu PETG-HF,  5 walls, 35% gyroid.  Used two Spax #8 2 ½" long screws to mount (link for reference).

Most likely overkill and could be reduced to save material – Securely attached to a stud, it is incredibly strong and easily supports my body weight.

Recommend printing in the shown orientation in the 3mf and image below (or flip 180 degrees, but then it would require supports).  This is the strongest orientation for the load path.
