Wanhao Duplicator/Maker Select filament guide with Allen key holder

Super basic remix of the filament guide to incorporate a tab to hold the Allen keys. The Allen key holes are tight enough that you can put them in vertically or horizontally (if you're worried about interfering with the print head when doing tall prints). Mine is in two colours (ran out of orange part way through but managed to hot-swap for red). That might make the pictures look a bit confusing.
