Thank you for this tutorial - I wasn't entirely sure about the continuous ink system, but you've clarified it for me and it seems pretty straight forward.
For a more professional finish and to enable full closure of the printer lid it would be a simple process to make a small slot with a Dremel Tool to the right side of the main body to pass the ink line through. The above CISS installation whilst quite informative would eventually lead to dust build up within the printer hence why ideally the ink line should be positioned more carefully within a slot. The person who made this video also commented on the noise of the unit when printing, this is simply because he has not placed the printer on a sturdy surface which would minimize some of the mechanical noise. Additionally rubber pads or BluTak beneath the base of the printer would facilitate in reducing vibration.
