What is orcaslicer-rpm?

This project makes it easy to install OrcaSlicer, a popular open-source program used to prepare 3D models for printing on FDM 3D printers, on Fedora Linux. OrcaSlicer itself takes a 3D model file, in formats like STL, OBJ, or 3MF, and converts it into instructions a 3D printer can follow, but it does not officially package itself for Fedora, so this repository fills that gap by building and maintaining an RPM package, which is the installer format Fedora uses. The project automatically checks for new OrcaSlicer releases every week and builds a fresh RPM package for Fedora 44 and newer whenever one appears, using GitHub Actions to do the building and publishing. The resulting package includes all the dependencies OrcaSlicer needs, sets up desktop icons and file associations so double clicking an STL, OBJ, or 3MF file opens it directly in OrcaSlicer, and generally makes it behave like a native Fedora application. For most users, installing is a two line terminal command using Fedora's COPR package repository system, or alternatively downloading a prebuilt RPM file directly from the project's GitHub releases page. Users who prefer building the software themselves from source can do so as well, though that requires installing a long list of development libraries first. The project is licensed under AGPL-3.0, matching OrcaSlicer's own license, and the maintainer accepts donations through Ko-fi.
