Built a little CLI/GUI tool for STL/3MF repair on Linux (MIT, open source)
Disclosure: I'm the developer of this tool.
No network calls at runtime — repair happens fully offline. Installation is pip-in-a-venv, doesn't touch AUR/pacman.
Bambu Studio's "Fix Model" only works on Windows (it uses Microsoft's Netfabb API — confirmed on their own wiki). OrcaSlicer has had open issues about this since 2023, and a community PR to add MeshLab-based fixing has been sitting unmerged for over a year.
I hit a broken mesh on Linux and didn't want to learn MeshLab's filter chains from scratch, so I wrapped PyMeshLab (hole closing, non-manifold repair) and
manifold3d (the same watertight-rebuild library Bambu Studio uses internally) into a small CLI + GUI + Dolphin right-click menu.
It's nothing groundbreaking — MeshLab could already do most of this manually, and there are paid/web tools too. I just wanted a right-click "fix" like
Windows has, so I made one and figured it might save someone else the same afternoon of digging through VCG filter docs.
Tested against Thingi10K samples (self-intersecting, non-manifold, multi-shell real-world models) plus a bunch of adversarial/malformed inputs.
Feedback welcome, especially if you hit a mesh it can't handle — I'd like to know.
