No setup needed, just download the STL or STEP files you need directly from the repository.
The Original Prusa SL1 repository contains the digital design files for a resin-based 3D printer made by Prusa Research. Rather than offering software, it gives you the 3D models of every physical part that makes up the machine, so you can understand its construction, print replacement pieces, or simply explore how the hardware is designed. The files come in two common 3D-model formats: STEP and STL. STL files are widely used for 3D printing directly, while STEP files contain richer geometric data that can be opened and edited in professional CAD software. Together, these files represent the mechanical components and the printed plastic parts of the printer. This repo is aimed at people who already own or are building a Prusa SL1 printer and want to inspect or reproduce its parts. For example, if a plastic bracket on your printer breaks, you could download the corresponding STL file and print a replacement yourself. Or if you are curious about the engineering behind the machine, you can open the STEP files in a CAD viewer to study how the frame, display, and moving parts fit together. The repository does not include the printer's firmware or assembly instructions directly, but the README links to both. The firmware lives in a separate GitHub repository, and the build manual is hosted on Prusa's website alongside the product page and community forum. This keeps the hardware design files focused and self-contained. Beyond serving owners, the project reflects Prusa Research's open-hardware philosophy: by publishing the full mechanical design, they make the printer more transparent, repairable, and modifiable for the community. It is a parts library, not a software project, but for anyone working with this printer physically, it is a useful resource.
A library of 3D design files for the Prusa SL1 resin 3D printer, providing STEP and STL models of every mechanical part so owners can inspect, modify, or print replacements.
Dormant — no commits in 2+ years (last push 2019-12-11).
No license is specified in the repository, so the design files are shared openly but without formal permission terms.
Setup difficulty is rated easy, with roughly 5min to a first successful run.
Mainly general.
