3D Extruder is an After Effects plugin from Ben Rollason for creating high-quality 3D extrusions. It's built to make that process light work inside After Effects, and it's listed as free in this catalog.
Compatibility reaches back a long way. The plugin runs on After Effects CS6, CC, CC 2014, CC 2015, CC 2015.3, CC 2017, CC 2018, CC 2019, and 2020, and its changelog records a later update for After Effects 2021. CS6 compatibility was added along the way, so older installs are covered alongside newer ones.
A demo video is available on YouTube for anyone who wants a look at the plugin before installing. For the latest version details and current licensing, the developer's page is the best place to check.
