Monoprice Maker Ultimate (Wanhao Duplicator 6) filament guide

I was using this filament guide (https://www.thingiverse.com/thing:1663067) which worked most of the time, but on new rolls of filament it sometimes pulled the filament over the reel to where it got caught on the filament holder. Additionally the printer head can hit the clip. This design clips into an empty slot on the back of the printer so nothing to worry about hitting it and it extends out from the printer further to prevent pulling the fillament off the reel.
