Best Free 3D Printer G-Code Files - Where to Find Them (2024)

3D printing has opened up a world of opportunities for creative designers and engineers alike, with one of its most important resources being G-Code files.

G-Code files will tell your 3D printer how to create your design. That’s why I wrote this article, to explore where to find the best free 3D printer G-Code files to help you get started.

Where Do You Find 3D Printer G-Code Files?

There are several ways to find 3D printer G-Code files online, including searching popular 3D printing websites, browsing through online forums, and using search engines.

Just be aware that G-Codes are tweaked to specific setups depending on the filament and bed type, as stated by one user. That means that you may need to edit your G-Code to get it printed properly on your setup.

I wrote an article about How to Modify G-Code in Cura which can be useful in these situations.

Here are some of the best places to find 3D printer G-Code files:
