Your 3D print library,
finally under control.

You have thousands of STLs scattered across Downloads, three external drives and a folder called new folder (3). 3D PrintVault pulls all of it into one searchable, thumbnailed library — and never moves a file it can't put back.

3D PrintVault wasn't prototyped on a demo folder. It was written to survive a real, messy 5,600+-model library — zips inside zips, macOS resource forks, files with corrupt timestamps, and a git checkout hiding in a design folder.

The situation

You don't have a library. You have a landfill.

Every printer owner ends up here. It isn't a discipline problem — it's that nothing in the pipeline was ever designed to file anything.

Everything is a zip named files.zip

Model sites hand you an archive with a nested folder, a licence text file, three plate variants and a README. It lands in Downloads and stays there forever.

You can't find the one you printed

Windows shows you a grey generic icon for every STL. A folder of 400 models is 400 identical rectangles, and search only works if you remember the filename.

So you never reorganise it

The one time you tried, a bulk move split a multi-part assembly across three folders and you couldn't get it back. Now you leave it alone.

What it does

A librarian for your printer.

Twelve tools that all point the same direction: get every model visible, findable and safe to move.

Sweep Downloads

One button finds every 3D file and archive in your Downloads folder, unpacks each zip into a proper project folder, fixes the names, and stages it all in an Inbox. You review the whole plan before a single file moves.

Real 3D thumbnails

STL, OBJ and 3MF files are actually rendered — not given an icon. Bambu and Orca 3MFs reuse their embedded plate previews. SVGs draw directly. Everything else gets a clean type badge.

Projects stay atomic

A 14-piece assembly is one thing, not fourteen. 3D PrintVault treats multi-file projects as a single unit and refuses to split them — no matter how you sort, filter or drag.

Undo anything

Every rename, move and regroup is written to a journal. The Activity view lists each batch with a one-click Undo — including the big scary ones you ran an hour ago.

Sealed folders

Mark your commercial or client work as sealed. 3D PrintVault indexes it, renders it and searches it — but is physically incapable of moving a file across that boundary in either direction.

Print counts that survive

Counts are keyed to the file's content hash, not its path. Rename it, move it, re-download it into a different folder — the counter follows the model.

Repair & Regroup

Files your old "organiser" scattered get clustered back together and offered to you as suggested project folders. You approve each one. Nothing regroups itself.

Duplicate finder

Finds byte-identical models across your whole library and shows you exactly how much space you'd reclaim — grouped, so you can keep the copy in the right place.

Open in your slicer

Right-click any model and send it straight to Bambu Studio, OrcaSlicer, Plasticity, Shapr3D, Fusion 360, FreeCAD, Rhino, Blender, Illustrator or Inkscape.

Print queue & stats

Line up what's printing next, see what you actually print most, and keep a daily maintenance checklist next to it all.

Filament inventory

Track spools by material, colour and remaining weight, so "do I have enough grey PETG" is a question you can answer without going to the shelf.

Nothing is ever deleted

There is no delete operation anywhere in 3D PrintVault. Junk, duplicates and stray installers go to a quarantine folder that only you can empty.

Sweep Downloads

Empty your Downloads folder in one pass.

Point 3D PrintVault at the folders where models land. It walks them, opens every archive, works out which loose files belong to the same project, and proposes a plan — then waits.

  • Zips become project folders. Nested single-folder archives are flattened; the original zip is kept, never destroyed.
  • Names get fixed. Cool Bracket (FINAL)(2).stl becomes cool_bracket_final_2.stl.
  • Source links are recovered where Windows recorded one, so you can get back to the original listing.
  • It only ever runs when you press the button. No watcher, no background job, no surprises.

Sealed folders

Your paid and client files never move.

If you sell designs, or you've bought models with a licence attached, the last thing you want is an organiser dragging them somewhere new. So 3D PrintVault doesn't have the ability.

Mark a folder as sealed and it becomes read-only to the file engine. 3D PrintVault still indexes it, renders thumbnails for it, searches it and counts prints from it — it simply cannot move anything in or out. The guard is enforced in the file layer itself, not in the interface, so there's no button that bypasses it.

  • Organised in place. Sealed folders are browsed as they sit on disk.
  • One deliberate exception. An optional airlock subfolder is the only route in — and only files already in it can come back out.
  • Visible everywhere. Sealed models carry a lock badge on the card so you always know what you're looking at.

Journal & undo

Reorganise without the fear.

The reason most people never tidy their library is that the last attempt was unrecoverable. 3D PrintVault writes every single file operation to a journal before it performs it, grouped into batches.

The Activity view is a plain list of what happened and when, each row with an Undo button that puts every file in that batch back exactly where it came from. A sweep that moved 600 files is one click to reverse.

  • Preview then apply. Every bulk action shows you the full plan first.
  • Batch-level undo. Not just the last action — any batch in the log.
  • Nothing to undo a delete from, because there is no delete. Removals go to quarantine.

How it works

Fifteen minutes from chaos to catalogue.

Install & open

Run the installer and 3D PrintVault opens in its own window. It serves itself from your own machine — nothing is uploaded, no account is created.

Point it at your folders

Tell it where your library lives, which folders to sweep, and which folders are sealed. Everything else is a default you can change later.

Sweep and review

Press Sweep. Read the plan. Untick anything you don't want. Apply — and watch the Inbox fill with named, thumbnailed, grouped projects.

File and print

Drag from the Inbox into categories, or let the rules do it. Right-click to open in your slicer. Tap the counter each time you print.

Formats

If your printer or CAD tool made it, 3D PrintVault indexes it.

Sixteen model formats are catalogued, searched and counted. The three highlighted below are rendered as true 3D previews in the browser; SVGs are drawn directly; the rest get a clean, readable type badge so a folder of STEP files still looks like something.

Who it's for

Two libraries, the same problem.

A shelf hobby and a print business hit the same wall — thousands of files nobody can find. They just need different things once they get there.

If you print for yourself

  • Find it againSearch names, tags, projects and notes
  • See it firstReal 3D previews, not filenames
  • Stop re-downloadingDuplicate detection by file hash
  • Know what you printedPrint counts, history and filament use
  • Clear the pileSweep Downloads into the right folder

If you sell what you print

  • Prove where it came fromSource link captured on import
  • Keep them separateCommercial files in their own roots
  • Protect your own workMy Designs stays sealed and in place
  • Answer questions laterCreation history and file-origin records
  • Work offlineNo account, nothing leaves the workshop

These are record-keeping tools. They document what you did — they don't determine whether a model's licence permits selling a print, and nothing here is legal advice.

What you get either way.

Nothing moves unless you say so

Indexing reads your folders. Your own designs are sealed and organised in place. Every move it does make is journalled and undoable, so trying it on a real library is not a decision you have to commit to.

It runs on your machine, fully

No account, no sync, no server — including the licence check. Unplug the network and everything still works, which is the point: your library does not stop being yours if a company changes its plans.

One payment, no tiers

$29 once, every feature unlocked, no library size cap and free updates through the whole 1.x line. There is no version of this that nags you for more.

Built against a real library

Developed against 5,600+ models across sixteen formats — not a demo folder. Try it on yours for 14 days before paying anything.

Pricing

Buy it once. It's yours.

No subscription, no seat count creeping upward, no feature held back for a "pro" tier that doesn't exist.

Questions

The ones people ask first.

Does 3D PrintVault upload my models anywhere?

No. 3D PrintVault runs a small server on your own machine that only listens on 127.0.0.1 — the loopback address. It isn't reachable from your network, let alone the internet. There is no account, no sign-in and no telemetry. Unplug your router and it works exactly the same.

Will it move my files around without asking?

No. Nothing runs on a timer or in the background. Sweep, Repair and every bulk action are buttons you press, and each shows you the complete plan before it touches anything. Folders you mark as sealed can't be written to at all.

What if it does something I don't like?

Undo it. Every operation is journaled in batches and the Activity view gives each batch a one-click Undo that returns every file to its original path. And because 3D PrintVault has no delete operation, the worst case is always recoverable — unwanted files go to a quarantine folder that only you can empty.

Do I need to reorganise my existing library first?

The opposite — that's the job. Point 3D PrintVault at what you already have, however messy, and let the scanner index it in place. Sweep handles the incoming pile, and Repair & Regroup proposes fixes for whatever a previous tool scattered. You approve each suggestion individually.

What are the system requirements?

Windows 10 & 11 (64-bit), a modern browser (Chrome, Edge or Firefox — Chrome or Edge recommended for the standalone app window), and enough free disk space for a thumbnail cache. 3D previews are rendered by your GPU through the browser, so any machine that can run a slicer can run 3D PrintVault comfortably.

Is there a Mac or Linux version?

Not yet. 3D PrintVault 1.0 is Windows-only. The underlying engine is cross-platform, so it's on the roadmap, but we'd rather say "not yet" than sell you something that half works. See the changelog for what's planned.
