Rui Raptor is at it again.  He’s created a great 2-part series showing what he believes are the top upgrades and addons you can install on your printer.  When you look at his results you can’t argue what he said are the best upgrades.  Like his other video series, this is another must-watch set of videos. 

Here is a link to the playlist.  Both videos should play from this link: https://www.youtube.com/playlist?list=PLY5Z2koT4Mi7jRWh3dbI20INwkT7Kwffm.
