Editorial interest 78/100 Selection signal · not a rating of the site

A browser extension for Amazon.com that compares 3D-printer filament listings by price per kilogram, sorts the results, and filters out unrelated items.

Landing page captured for the 2026-11-04 issue.

For: People comparing 3D-printer filament on Amazon.com
Worth noticing: It handles bundles, mixed unit sizes, and listings priced only per ounce, and loads later result pages in the background.

Field notes

The homepage describes separate ways to install the tool: through the Chrome Web Store, as a userscript, or by loading the source folder in developer mode. It says the extension activates only for filament searches and that filters sync across Chrome devices. The project identifies itself as GPL-licensed and says it uses no tracking, analytics, accounts, or servers.
