These mounts can be attached to tree trunks using large zip ties. Then pixel node strips can be hung by feeding them up through the mount, making a small loop in the strip, and using small zip ties to hold the loop in place. I've also included another STL for a similar mount at the bottom of the strip that uses a bungee ball to keep tension on the strip.
Print both mounts upside down with the flat top surface on the build plate.
