This model mounts to the voron 2.4 handles which can be found here.
Remove the top middle M3 screw from the handle and add in a 20mm screw in its place to mount this tray to the side of the handle.
The section for holding a piece of 2020 extrusion is there as a hot-tolerant surface for placing freshly-changed nozzles. I change nozzles relatively often and being able to set them on a surface that won't melt is very handy!
I recommend printing the right angle support with high infill, as it's not the sturdiest thing in the world. But it's strong enough for some paper towels.
