Flashforge Creator 3 50x70mm deep spool adapter

I found some good quality ABS (without the stink or the warp, win!) that came in rather deep spools. The original spool holders of the Creator 3 won't hold those spools very well, they kept on leaning down with the risk of falling.
Plus I couldn't close the side door without the spool being jammed.

Solution: a 50mm OD and 70mm deep spool holder that clips in place over the original one, now the spool moves without any wobble and there's no jamming or tangling.

I've also trimmed the ribs of material on the inner face of the side door, it's not a stressed part so it's better to have the inner surface smooth without any interference for the filament spool.
