Printer V-Slot Rail Tray - For catching debris or holding tools

My printer homes directly over the v-slot rail, and as it warms up it drips tiny wisps of filament into the slot. As it's annoying to pick filament out of the slot, I made this simple tray.

Alternately one can slide it so it's not directly under the nozzle in which case it's great for holding a USB stick, resting some pliers, screws, etc.
