Notes from the vault.
Release notes, field guides, and hard-won lessons from organizing real 3D-printing workflows.
Clean a downloaded STL pack on ingest
What actually cleans a downloaded pack: content-hash dedup on ingest during ZIP import, not mesh repair or a manual duplicate sweep.

113 entriesMakerspace print library: roles, logins, audit
PrintStash handles makerspace access control: per-member logins, collection roles, per-printer permissions, optional OIDC, audit trail with secrets redacted.
Manage files across multiple Klipper machines
Per-machine file management works up to about two printers, then becomes the small-farm bottleneck. Where the line sits, and what a fleet-queue library changes.
Which self-hosted tools connect to Spoolman?
Moonraker, an OctoPrint plugin, and a few bridges feed Spoolman directly. Where each connection lives, and which layer ties consumption to a finished print.
Sync a printer's SD card with a central library
Two-way SD sync only exists on Klipper, where the card is a server folder. Elsewhere pick a direction of truth: push from the library or pull recorded history.
Does your printer limit self-hosted tools?
Buying a printer fixes your control stack. Your model library need not follow: what five printer interfaces expose, what stays portable, and what is still beta.
Back up Docker volumes for a 3D print library
Which volume holds the database, model files, and encryption key, why the built-in archive beats copying a live volume, and what a snapshot cannot restore.
Track real filament cost per print, self-hosted
Cost per print is grams over 1000 times your price per kilogram. Which half a self-hosted stack measures rather than estimates, and where the number ends up.
PrintStash v0.12.1: container startup reliability
Why some API containers crash-looped right after their database migrations finished, the two environment variables that fix it, and who needs to care.
3D printer ecosystems for self-hosted software
Klipper machines run any software, Bambu needs LAN mode plus Developer Mode, Prusa sits in between, and Elegoo is split. What each interface lets software do.
Send prints to an Elegoo Centauri Carbon
PrintStash v0.11.3 added G-code upload for the Centauri Carbon and Carbon 2. How SDCP and MQTT differ, what setup needs, and how thin the hardware evidence is.
Can you manage a 3D printer farm from a phone?
PrintStash runs on a phone as a PWA: the farm at home or away, over WireGuard, Tailscale, alerts via ntfy or Telegram. Offline means the shell, not the library.
Manage multiple 3D printers from one dashboard
What a self-hosted multi-printer dashboard shows: live state for every machine of any brand, aggregate stats over prints, and where the numbers stop comparing.
Put a self-hosted 3D print library behind SSO
PrintStash supports OpenID Connect, so members sign in with the identity provider you run. What group mapping does and does not control, and what stays manual.
Customer job submission for a small print farm
Intake sits in front of the library, not inside: an email or a file drop, a rule for files to reach production. What each channel costs and where the job ends.
What makes a print library production grade
Four testable properties that separate infrastructure from a hobby project, an honest score for PrintStash at v0.11.4, and what the category still lacks.
Self-hosted print management for Elegoo
Your Elegoo sets the ceiling: the Neptune 4 runs Klipper for full capability, while the Centauri Carbon uses a beta native provider without file inventory.
Sync STL files between a PC and a NAS reliably
Pick a direction and stick to it: a mount, a one-way rsync push, or Syncthing for two-way. Plus what changes when a library indexes the NAS folder in place.
PrintStash v0.12.0: material-aware dispatch, safer first run
Preflight compares material and nozzle before a send. Fleet batches gain copies and release gates. Startup no longer deletes unindexed files. API ships lite.
Queue and schedule prints across a printer farm
What a fleet queue does: the three routing strategies, what makes a printer eligible, drain and maintenance windows, and the /api/v1/fleet endpoints in full.
Filament, cost, and which revision worked
Where a print record should live, which numbers are measured and which estimated, and how to read filament use and cost per model, revision, and printer.
Is there a better Moonraker file browser?
Moonraker's file manager lists sliced output on one machine. How to tell whether you need a different front-end, a library behind it, or neither.
A central G-code repository for your print farm
A central G-code repository is one versioned store slices land in and printers read from. How the known-good verdict is recorded, and how files reach machines.
Easiest 3D printing tools for Docker Compose
Which 3D printing tools install in one Compose command, by services and values to edit first, plus what you do by hand. Includes the minimal PrintStash install.
Self-host a private Thingiverse-style library
How much of a public model site you can reproduce: previews, search, tags, and collections, but no catalogue, comments, or galleries, plus the sharing story.
Does a small print farm need an ERP?
Quoting, stock, and cost accounting live outside a file library. What FilaOps and Printago cover, why OctoFarm is not it in 2026, and where PrintStash stops.
Get reproducible prints across a fleet
Deterministic slicing makes the file identical, not the machines. What a pinned build pins across a fleet, and where the machine-to-slice record lives.
Repair non-manifold STL errors before print
What holes, normals, self-intersections, and non-manifold edges do to a slice, which tools report and which fix them, and two common repair tools unsupported.
Organize STL files by fixing how they arrive
Model libraries decay one file at a time, not all at once. The four ways files enter, what to do at each, and why intake beats another folder reorganization.
Managing the STL library after the first scan
What changes once a library is indexed: scan cost, taxonomy rot, browsing performance at scale, and the backup boundary that catches people out.
Version control for 3D model files: the limits
Sliced output gets labels, outcomes, and a recommended marker. Source meshes get an ordered history and nothing else. Where the line falls, what to do past it.
What an open source STL library license means
AGPL and Apache 2.0, what each obliges when you self-host a 3D model library, plus the two things open source does not guarantee regardless of license.
What is STL file management software?
Defined against the five tools it's confused with: cloud drives, slicers, print controllers, model marketplaces, and organizers. What belongs and what does not.
Organize your STL library, keep it simple
Four ways to keep a model collection in order, from a folder tree to a library wired to the printers, and which one your collection has outgrown.
Can you version control G-code like software?
Git handles the inputs well and the sliced output badly. How a pinned-slicer build regenerates G-code deterministically, and where the print record has to live.
Should you store print settings in 3MF or STL?
STL cannot hold settings, so the question is when a 3MF project earns its keep, which format keeps the geometry, and where a library reads settings instead.
Automatically tag and organize 3D model library
Slicer metadata, printer profiles, and content hashes arrive untagged. What a model is for never does, so keep a short tag list and automate the rest.
Managing a mixed Klipper and OctoPrint fleet
One library for machines that speak different protocols: what each provider lacks, how to keep 0.4 and 0.6 slices straight, and why cost data differs.
Auto-upload OrcaSlicer G-code to your library
Set up OrcaSlicer's post-processing hook so every export lands in a self-hosted library, and what it does not do: file the slice as a revision.
Print over LAN without vendor cloud services
Which printers keep working with the vendor cloud off, how to set up a fully local slice-to-print workflow, and what you give up by leaving the cloud behind.
Sync a printer's files with a central library
Printer file sync indexes and correlates the machine's G-code against your library instead of copying files back, and tells you when it guesses.
PrintStash v0.11.4: large libraries and stricter data safety
Global cursor browsing, bounded archive work, safer deletion and sessions, a single-process deployment contract, and SeaweedFS for the bundled S3 profile.
Version-control slicer profiles across printers
Put your slicer's preset files in Git, keep them in sync, and use the settings baked into each G-code file to prove which profile produced a good print.
What to look for in a self-hosted 3D manager
Nine criteria that separate a model library you keep from one you abandon, each with a test you can run on a trial instance, plus the things people overweight.
PrintStash v0.11.3: Centauri Carbon upload and safer backups
Elegoo Centauri Carbon and Carbon 2 receive G-code over the network, spool selection warns before a print runs out, and backups capture a consistent snapshot.
Best print farm software for Klipper printers
The answer depends on the bottleneck: PrintStash for the file library and fleet queue, O.D.I.N. or SimplyPrint for monitoring, print-farm-manager for dispatch.
Send G-code to multiple printers from one app
How a self-hosted fleet queue routes G-code across printers: what one queued job means, how least-busy routing works, and which providers can receive files.
Find duplicate 3D models by content, not name
'By content' means two things: byte-identical hashes (dedupe tools) or geometric similarity (CAD part search). Which you need, and what PrintStash does.
Connecting OctoPrint to PrintStash
Set up the beta OctoPrint provider with an app key: live status, upload and start, remote file inventory, and job control beside your existing instance.
