Free STL Files & 3D Printer Models in 5 Easy Steps

  1. Browse this list of 3D printer model sites for inspiration and ideas. Go ahead, take your time, we’ll be here when you get back.
  2. Download the free STL files for your chosen model. Click on the links to visit the site where the files are hosted, where they are available to you lucky people at no cost. Please note that some sites may require registration before downloading.
  3. Slice the STL file to prepare it for 3D printing, converting it into G-code. Whether you use an open source application like Cura or a paid solution like Simplify3D, slicing is a critical step for the quality of your model. Open the STL file and tinker with settings like infill, layer height, and supports.
  4. Print the file after the slicing process is complete. Save the converted G-code file and send it to your 3D printer, either using a USB connection, SD card, or network connection. Now you’re ready to get printing!
  5. Alternatively, use a Printing Service if you don’t have access to a 3D printer. Simply upload the STL files to our Best Price 3D Printing Service to have your favorite models 3D printed.
