Like a lot of people here, my 3D-printable models were scattered everywhere — bookmarks across MakerWorld, Printables, and Thingiverse, random downloaded ZIPs, half-organized folders. I built Thingport to fix that for myself, and figured it might be useful to others here too.
What it does
Personal, self-hosted library for your 3D printing models
Import directly from MakerWorld, Printables, and Thingiverse links (or whole collections)
In-browser 3D preview (STL/OBJ/3MF) — no slicer needed just to look at a model
Organize with categories, collections, and tags (with casing-aware merging, bookmarkable tags, etc.)
Keeps the original source link and metadata alongside the files
Multi-user with admin controls (users, logs, storage settings, instance-wide update checker)
Dark mode, multi-language UI (English/Lithuanian so far)
Two small companion tools, if you want them
Thingport Grab — a Chrome extension that imports a model straight from MakerWorld/Printables/Thingiverse's own page, no copy-pasting links
Thingport Bridge — a tiny helper so "Open in Slicer" actually works for slicers (Bambu Studio, PrusaSlicer) whose own URL-protocol handlers only trust a domain allowlist your self-hosted instance isn't on
