Your 3D Prints,
Finally Organized
STL Stash sorts your entire STL and 3MF collection into print-ready Prints automatically. It figures out which files belong to the same model, tracks what's ready to slice, and sends prints to your slicer in one click.

3 filesYou've subscribed to nine Patreons and your downloads folder hates you.
Every month, more files. New monsters, new terrain, the pre-supported versions, the FDM versions, the lore PDF nobody reads. Half of it sits in folders named “to print eventually” that you will never open again.
STL Stash fixes the part marketplaces don't - what happens after the download. Drop your files in or paste a Printables URL. AI groups everything into Prints, reads companion notes for print settings, and pulls metadata from source sites.
Then the real
workflow begins
Know what's ready.
Every Print has a checklist: add parts, set quantities, check them off as you print. You see at a glance what's ready for the printer tonight and what still needs work.
One click to your slicer.
Found the file you want? Send it straight to OrcaSlicer, Bambu Studio, PrusaSlicer, or Cura. No more digging through nested folders looking for the right version.
What's in the box, today.
Everything below is shipping. Not a roadmap, not “coming soon.”
Upload & Import
Drag folders or individual files. Multi-gigabyte uploads run in the background. Review everything before it hits your library.
Collections & Tags
Group your prints however your brain works. By campaign, by creator, by faction. Multiple collections per Print, no nesting nonsense.
Sharing
Share Prints or Collections with permissions, licensing, and expiration controls.
Search
Find any file by name, notes, tags, or creator. Results in seconds, not hours.
Notes & Images
Attach reference photos, paint notes, scaling info. Your library becomes your workshop.
Full Export
Your files, always yours. Export your entire library as a ZIP whenever you want.
Keep your files
in your own cloud.
Already organize your library in Dropbox? Connect it and manage your 3D prints without moving your originals. Dropbox stays your source of truth; STL Stash becomes the library layer on top - organizing, previewing, reviewing, and sharing.
We're developers on the Dropbox API. Connect your account in two clicks and your existing folders become a searchable, AI-organized library. More storage providers coming.
Built on trust,
not lock-in.
The 3D printing community has been burned by platforms that change rules overnight. We built STL Stash to be the opposite.
No Lock-In, Ever
Cancel any time. Export your entire library in standard formats. No waiting periods, no export fees. Your STLs stay STLs.
Private by Default
No public gallery, no discovery feed. Your Stash is yours alone. Sharing is always opt-in - nothing is visible unless you create a link.
No AI Training on Your Files
Your uploads are never used to train any model. AI organizes your files at your request - that's the whole job. No generating, no scraping.
Honest Billing
Stripe handles payments - your card details never touch our servers. No surprise upsells, no retention dark patterns. Cancel in two clicks.
Built for the people
who actually need this.
Tabletop miniatures and terrain are our primary audience - that's where the file chaos is worst. But if you print functional parts, cosplay, or gridfinity, it works the same way.
“I have 47 unprinted miniatures and a guilty conscience.”
Hobbyists & Makers
The Patreon backlog crew
You've downloaded hundreds of files from Printables, Thingiverse, and six different Patreons. Half are in folders named “new” or “misc.”
Creators & Designers
Your portfolio is your business
You design models and need to manage versions, organize by project, and share Prints with customers or collaborators.
Print Farm Operators
Spreadsheets aren't cutting it
You're running multiple printers and need to know exactly which parts are done, which are queued, and which still need slicing.

Use our storage, or bring your own Dropbox. Every feature is included either way. No tier games, no add-on traps.
First 3 months at $7/month during beta. After that, $10/month.

Where We're Headed
STL Stash is in beta and growing fast. Here's what's live and what's coming.
Core App & AI Organizer
Full Print management with AI-powered auto-organization, collections, tags, search, print checklists, sharing with permissions, and direct-to-printer workflow.
Bring Your Own Storage (Dropbox)
Connect your Dropbox and keep your originals where they already live. STL Stash indexes existing folders, writes new uploads straight to Dropbox, and syncs renames and deletes automatically - no migrating your whole library.
Import from URL
Paste a Printables URL and STL Stash downloads the files, pulls the metadata - description, license, author, print settings - and pre-populates the review modal. No manual upload needed.
Companion Notes Pipeline
Upload files alongside a readme.txt or notes.md and STL Stash reads them for print settings, resin exposure, brand names, and descriptions. Suggestions route through the same accept/dismiss UI.
Paid Sharing & Subscriptions
Offer paid access to your Print collections through shareable links with built-in payments. Charge one-time fees or recurring subscriptions for your premium files.
Desktop App
Access your local files directly alongside your own storage, paired with STL Stash's online services for syncing, sharing, and AI evaluation. Mac, Windows, and Linux.
3rd Party Integrations
Direct integrations with popular slicers, printer firmware, and platforms like OctoPrint, Bambu Cloud, and Prusa Connect.
