The full list of possibly effected sites is apparently more than 4 million long. Linked below is a site with the full list, a “notable” list, and a list generated by cross-referencing against Alexa’s top 10,000 sites.

Makezine.com and thingiverse.com are the only two that jumped out at me as sites that Glowforgers might also have accounts with, but if you find more please post them below.
formlabs.com (use the “forgot your password” option to change it, also, since the “log out” button/link doesn’t seem to function, use a private browser window to gain access to the “forgot your password” option)
