Print Organizer is a Mac app that brings order to your 3D print collection — track every file, preview models, launch slicers, and back everything up.
Click around — this is a live simulation of Print Organizer.
Copies every file — including NAS drives if mounted
Copies local files, records paths for linked files
Records all paths, copies nothing
Simulated demo — no real files are created or modified.
Every feature was designed around how people actually use their 3D print library — not how a file manager works.
Organize files into color-coded collections, then create sub-folders inside them. Miniatures → Fantasy → Characters — as deep as you need.
STL, OBJ, 3MF, and AMF files render as interactive 3D models — drag to rotate, watch them spin. STEP and F3D files show QuickLook thumbnails.
Mark each file as Not Printed, Queued, Printing, Printed, or Failed. Filter your library by status and see what's in your queue at a glance.
Open any file directly in your preferred slicer — Bambu Studio, PrusaSlicer, Orca Slicer, Cura, and more. Add custom slicers for any app on your Mac.
Add tags for quick filtering, write notes about print settings or problems, log filament usage in grams, and record estimated print time.
Three backup modes — Full, Smart, and Paths Only — handle everything from a portable self-contained archive to a lightweight metadata snapshot for NAS setups.
Keep files on your NAS or external drive — no copying needed. Print Organizer links to them directly, so nothing is duplicated on your Mac.
Set the filament color for each file and see the 3D model rendered in that color. Change the color and the preview updates instantly — no reload needed.
Full-text search across file names, tags, notes, and collections. Sort by newest, oldest, name, or print status — instantly, with no loading.
Choose how your files are managed — copied locally or kept exactly where they are.
Click Import and choose any supported file or an entire folder — Print Organizer scans it recursively and imports every supported format it finds. Each file is copied into the app's storage on your Mac.
Because the file lives inside the app, it's always accessible even if you move, rename, or delete the original. Great for files downloaded from the internet or exported from a CAD tool.
Click Link File and choose files from your NAS, external drive, or any network location. Print Organizer saves a reference to where the file lives without copying a single byte to your Mac.
The file stays exactly where it is. When you open or send a linked file to a slicer, it reads from the original location. If the drive is offline, the metadata, status, and tags are still fully visible — you just can't open the file until the drive is back.
Blue formats render as interactive 3D models you can drag to rotate. Others use QuickLook thumbnails generated by your installed slicer apps.
Three backup modes cover every setup — from a single Mac to a multi-machine workshop with a shared NAS.
Copies every 3D file into the backup package — including NAS and external drive files if they are mounted. The result is a completely self-contained archive that works on any Mac without needing any drives attached.
| Local files | Copied |
| Linked files | Copied if online |
| Backup size | Large |
| Works on new Mac | Always |
Copies files stored inside the app but just records paths for linked NAS and external drive files — they stay where they are and get relinked automatically on restore when the drive is accessible.
| Local files | Copied |
| Linked files | Path recorded |
| Backup size | Medium |
| Works on new Mac | Local files: yes |
Records the location of every file without copying anything. The backup is tiny (a few KB of JSON). On restore, all files are relinked from their original paths — every drive must be accessible.
| Local files | Path recorded |
| Linked files | Path recorded |
| Backup size | Tiny (KB) |
| Works on new Mac | Drives must match |
Regardless of which mode you choose, every backup contains your complete collection structure, all file names, tags, notes, filament colors, print times, and statuses, plus all slicer preferences and app settings. The mode only controls whether the actual 3D file bytes are copied.
The backup is a plain folder you can open in Finder and inspect. No proprietary format, no lock-in — just JSON files and a files/ subfolder.
Click Import to copy files into the app, or Link File for files on a NAS or external drive. Drop an entire folder to scan it automatically.
Right-click in the sidebar to create a collection and pick a color. Drag files onto it to assign them. Right-click a collection to add sub-folders inside it.
Right-click any file card to change its status. Click Edit to add tags, write notes, log filament weight, and record estimated print time.
Go to Settings → Slicers to choose which apps appear. Then click any file to reveal one-click launch buttons for each slicer.
Open Settings → Backup, choose Smart mode (recommended), and click Export Backup. Save the folder to a USB drive, cloud storage, or anywhere you like.
Install Print Organizer on the new Mac, open Settings → Backup, click Restore Backup, and point it at your backup folder. Everything comes back.
.printorgbackup folder. The app restores all collections, metadata, and settings, and copies 3D files back into its storage (Full and Smart modes). If you used Smart or Paths Only mode with NAS files, mount those drives before restoring so the files can be relinked.~/Library/Application Support/PrintOrganizer/Files/. This folder is inside your macOS user profile and is included in Time Machine backups automatically. Files added via Link in Place are never copied — they stay at their original location and nothing is written to Application Support for them.
