Fillament guide and cleaner for flashforge dreamer

This fillament guide will work well with my "External mount filament for flashforge dreamer".
It has removable cap in which you can place cloth for dust cleaning.
It easily connects to the external sides of the flashforge dreamer.
It's main purpose though, is to prevent from the fillament to jump off the spool when the printer head travels back towards the spool. This is why it has this downward angle.
