Anet A8 gantry mounted filament guide

As I have a cable chain on my Anet A8 I find the filament rubs against the side.

While I already have a filament guide mounted at the top of the machine I needed something to prevent it rubbing against the chain.

I printed mine with 100% infill and 4 perimeter walls but you should be able to get away with less.

I used 3.5mm x 18mm screws and simply used a nut on each for spacing (I didn't have any smaller screws lying around.
