Step 3 in the link below has a link to the Mini Graphical LCD that does not work. I believe the location of the GLCD was changed but the link was not updated.
Step 3 of this guide: https://ohai.lulzbot.com/project/installing-your-lulzbot-mini-graphical-lcd/accessories/ has a working link. I've clicked through the rest of the links on this page and they seem to be working for me. Closing out, reopen if they're found to be broken.
