Flashforge fillament holder

This part was directly derived from [thing:805717]. It has been modified to add a stop at the bottom of the tube holder to prevent to filament guide tube from moving too far down. Depending on your arrangement you may have to shorten your filament guide tubes about an inch.

As with the original, this also has the advantage that it can be printed without support or rafts.

Licenced under CCSA because I can't choose a more permissive licence.
