You don’t have to design everything

Designing your own models is a superpower - but sometimes you just want to print something cool tonight. The 3D printing community shares millions of free models you can download, slice, and print. Many are also remixable, meaning you can open them and make them your own.

The 3D model-sharing ecosystem: download, print, remix, and share back

How to download and print a model

Find a model

Search a library for what you want - “phone stand,” “dragon,” “desk organizer.” Check the photos and comments to see how well it prints.

Download the STL

Download the .stl (or .3mf) file. Read the maker’s notes - some suggest specific settings or supports.

Slice it in Cura

Open the file in Cura, scale it if needed, choose your settings, and slice.

Print it

Save to your microSD card and print on your Ender 3.

Most models are free for personal use. Check the license before selling prints or reposting a design as your own.
If you remix someone’s design, credit the original maker.
When you design something cool, consider uploading it so others can enjoy it too.
Post a photo of your print to thank the designer and help others see how it turns out.
A great way to keep learning is to download a model, then open it (or a similar one) in Tinkercad and change it. Remixing existing designs is how many makers learn to design their own.
