Tool Holder with Filament Cleaner for Wanhao Duplicator I3

So i loved the tool holder but i wanted to also have a fixed filament guide/cleaner
i have threaded the outgoing hole post-print to screw in a tube fitting allowing me to have a 4mm guide tube to the print head, hopefully to help maintain consistent drag on the extruder
i have also extended the allen key holder upwards so the keys can point inwards or outwards without hitting the scraper or machine frame
