Free 3D Prints for the Elegoo Neptune Series

Mods, tool organizers, and benchmark prints for Neptune 3 and 4 owners

The Elegoo Neptune line is the budget workhorse of countless print farms and first setups, and its owners are prolific modders: screen protectors, tool drawers, spool rollers, cable management, and gantry accessories designed around the Neptune's frame fill the most-saved lists.

This collection curates free 3D models for the Neptune 3 and 4 series from Cults3D, MyMiniFactory, Thingiverse, and other platforms: printable mods and organizers, calibration and benchmark prints, and community-favorite functional models for the 225 mm class beds. Every model is free to download from the original creator's listing.

Neptunes love PETG for functional parts and PLA for everything else. Print the tool drawer first: every Neptune owner ends up with one eventually, so you may as well start there.
