Controlling Klipper-powered 3D printers from a single browser workspace, Mainsail delivers a responsive web interface for monitoring print jobs, tuning kinematics, and managing multi-printer farms in real time. Makers and print farm operators monitor extruder and heated bed temperatures, fan speeds, and toolhead coordinates live on customizable dashboard layouts. An integrated file manager and syntax-highlighted editor let you upload G-Code directly from your slicer, organize print job queues, and modify Klipper configuration files (`printer.cfg`) without opening an SSH terminal. Interactive 3D visualizations render bed mesh heightmaps for first-layer leveling diagnostics alongside a real-time 3D G-Code toolpath viewer that tracks layer progress. Multi-webcam streaming, automated timelapse recording through `moonraker-timelapse`, Spoolman filament spool tracking, and mid-print object exclusion help salvage multi-part plates when a single model detaches. You can also organize parameterized Klipper macros, switch smart relays or Tasmota power plugs, and audit historical job success rates and filament consumption.

Over a million active instances make OctoPrint the standard web interface for consumer 3D printers - Gina Häußge's Python application, the center of the printing world since 2012. It talks to your printer over USB serial and turns every browser into a control panel: upload, organize, and start G-code prints; watch hotend and bed temperature graphs in real time; drive the print head manually; adjust feed rate, flow, and fan speed mid-print; and hit an emergency stop if things go wrong. The G-code visualizer renders the current layer in sync with the job, and a connected webcam adds a live feed plus automatic timelapse recording of every build. What keeps OctoPrint ahead is its plugin ecosystem - 300+ community plugins installable from the built-in manager. Highlights include Obico's AI spaghetti detection that pauses failed prints automatically, OctoEverywhere for tunnel-based remote access, Bed Level Visualizer's 3D mesh of your bed surface, PrintTimeGenius for accurate time estimates, Exclude Region to abandon one failed object mid-print while others continue, and Firmware Updater to flash Marlin or Klipper without SD-card shuffling. Event hooks fire notifications when prints finish or fail, and a full REST API supports slicer integration and custom automation. AGPL-licensed.

Running out of filament mid-print ruins multi-hour 3D printing jobs, and Spoolman solves this by tracking every gram of plastic across your entire workshop in a centralized, self-hosted inventory database. Connected directly to Klipper, Moonraker, Mainsail, Fluidd, OctoPrint, and OctoEverywhere, the service deducts filament weight automatically over live WebSockets as your extruders run. You can import manufacturer specifications from the community SpoolmanDB catalog, filter your library by color similarity or material type, and organize spools on a drag-and-drop board grouped by storage location or custom fields. A built-in label designer generates printable QR code sheets containing spool metadata, while NFC and RFID tag scanning lets you tap a physical roll against an ESPHome reader or Android phone to pull up its record immediately. Multi-printer workshops can monitor concurrent consumption from several machines simultaneously, expose inventory metrics to Prometheus and Home Assistant, and query stock levels through a Model Context Protocol (MCP) server.

Print Farm Manager runs your whole 3D printer farm, whatever mix of brands it contains, from one self-hosted dashboard that watches every machine and feeds work to the idle ones. The live fleet view refreshes every 15 seconds with each printer's status, progress, and time remaining, so a walk past the screen replaces a walk past every machine. Define projects and parts, upload the G-code, and the scheduler assigns jobs to whichever suitable printer frees up next. When a print finishes, an operator confirms the result before the next job starts, which stops one failed bed from wasting a queue of filament overnight. Prusa machines connect over PrusaLink, Elegoo over SDCP or MQTT, Bambu over MQTT and FTPS with AMS slot selection, and Klipper and OctoPrint machines over their REST APIs, all in the same fleet. Onboarding a roomful of printers takes one CSV import instead of fifty afternoons of clicking, and the TV dashboard mode turns a spare monitor into a shop wall status board. The whole farm, configuration and job history included, exports to a single JSON file for backup or migration. It is built for a trusted local network, reached on port 3000 over the LAN or a VPN.

Command and automate your entire fleet of 3D printers without relying on proprietary cloud services using Bambuddy, a self-hosted management hub that delivers local network control, print scheduling, and job archiving for Bambu Lab hardware. Print shop operators can route slicing output directly from Bambu Studio or Orca Slicer through virtual printer proxies that emulate physical machines while automatically cataloging print files in a searchable 3D repository. The automated dispatch engine assigns queued gcode files to available printers based on required nozzle temperatures, build plate dimensions, and matched multi-color filament slots. Users can inspect live camera streams across multiple printing beds simultaneously, verify empty build plates before dispatching new jobs, and generate stabilized timelapse videos with custom music. Integrated smart plug connectors automatically cut power to idle machines when print cycles finish and trigger push notifications to Discord or mobile devices if thermal anomalies or mechanical pauses occur. Farm managers can schedule maintenance alerts based on cumulative motor runtime, track spool inventory levels across storage locations, and synchronize printing configurations across duplicate hardware setups.

The bracket you printed last spring sits in some folder, on some drive, under a filename you no longer remember; GyroidVault is the searchable library that ends the hunt, where every model can be inspected in 3D, tracked through its prints, and sent to a printer without touching a slicer queue. Point it at your existing folders on a NAS or server and it indexes STL, 3MF, STEP, OBJ, G-code, binary BGCODE, and even Fusion 360 files non-destructively, generating thumbnails and 2x2 collages while a duplicate finder flags identical copies by SHA-256 hash. Opening a model launches Studio 2.0: orbit the mesh, jump between isometric, top, front, and side cameras, switch between solid, wireframe, and X-ray shading, try filament colours live, arrange multi-part assemblies on one build plate, and snapshot your favourite angle as the cover. Sliced files give up their secrets too, with layer-by-layer toolpath previews plus infill, temperatures, filament weight, and estimated cost extracted automatically. From the same page you can fire G-code straight to a Moonraker or Klipper printer, open the file in OrcaSlicer, Bambu Studio, PrusaSlicer, Cura, or Creality Print, log each print with its material and outcome, and share a model through an expiring public link. Collections, version histories, custom metadata fields, and role-based accounts keep a growing print farm library tidy for everyone who uses it.

Every printing household eventually drowns in files named final_v3_REAL.gcode, and PrintStash is the library that brings order to your models, G-code, and print history. Upload STL, 3MF, OBJ, STEP, and other formats directly, or point it at a folder or NAS share and let it index everything in place without overwriting originals. Each model page pairs a 3D preview with its recommended G-code, the slicer settings behind it, and one-click actions to open files in your slicer. Revisions carry needs-test and known-good labels, so the version that printed beautifully is never confused with the experiment that delaminated. Connected printers report live temperatures and progress, accept sent G-code, and take queued copies across printer groups, with material or nozzle mismatches blocking automatic routing before they waste filament. Print outcomes feed time and cost tracking per model, and an optional Spoolman integration keeps filament inventory honest. Collections, tags, filters, favorites, and saved views keep a growing vault browsable, and optional AI search with local models finds models by description. Verified backups, file audits, trash recovery, user permissions, API keys, and OIDC single sign-on round out the administration side.

Authors delete listings, and the 3D models go with them, so Thingport stores its own copy of every printable file you import, in a self-hosted library you control. Ten sites feed the library, including MakerWorld, Printables, Thingiverse, and MyMiniFactory: paste a link or use the browser extension, and a model arrives with its files, photos, description, tags, author, and source link. Synced collections add newly bookmarked models as often as every hour. Files you already own come in as STL, 3MF, STEP, OBJ, or LightBurn uploads, ZIPs, folder trees, or drops into a watched consume folder. Each model gets an interactive 3D viewer with a thumbnail for every plate of a multi-plate 3MF. On first open, a check flags surface holes, non-manifold edges, flipped faces, and loose fragments before you slice. Sort with nested categories, collections, and tags, mark favourites, and find anything with full-text search. Optional AI sorts imports into your categories and tidies descriptions, using a local Ollama model or a cloud API. Open any file in Bambu Studio, OrcaSlicer, PrusaSlicer, Cura, or Creality Print, or download a model, tag, or collection as one ZIP. Every user gets a separate library, with invite-only registration, email verification, and single sign-on. A dashboard shows library statistics, profiles show a year-long activity heatmap, and MCP lets an AI assistant work with the collection.

MakersVault gives your scattered 3D print files and creative artwork one searchable home, so you stop loading models into a slicer just to remember what they are. You create folders and subfolders for projects, then drag and drop single files, batches, or whole folders straight into the library from your browser. Every model tile carries a rendered preview, and double-clicking opens an interactive 3D view you can rotate and inspect before downloading anything. Tags attach to any file, batch tagging covers many selected models at once, and tag tabs plus sorting by name, size, type, or folder keep large collections browsable. Notes on individual files record print settings, filament choices, or assembly reminders right beside the model they describe. Imports pull models directly from MakerWorld, Thingiverse, and Printables links, and zip archives prompt you to keep only the files you actually want. Supporting documents ride along with each model and travel inside its ZIP downloads, and prepared print data surfaces printer, material, nozzle, and time estimates on the card. The Open in Slicer button hands a model to your configured slicer through the desktop bridge, and themes from light and dark to neon accents restyle the whole workspace.

Pretty Please Print turns one office's shared 3D printer into an invite-only request board: colleagues upload a model and follow it from request to delivery. Requesters upload an STL or 3MF file, or start from a Printables link the owner enabled, and the mesh renders in the browser, auto-framed and draggable, so everyone checks the geometry first. Every request becomes a ticket that the printer owner moves through Requested, Accepted, Printing, and Delivery, or declines with a reason, and requesters can withdraw their own print before it reaches the bed. Slicer specifics like layer height, infill, supports, and temperatures ride along as notes on the ticket, a low, medium, or high priority keeps the owner's queue ordered, and a conversation thread on each ticket replaces lost chat threads. The owner curates the materials and colours on the shelf, with swatches and a rainbow whatever option, and defines the tips requesters can offer, preferred ones starred. Finished jobs collect in a filterable history: Print again reopens the form with the model copied server-side and fields adjustable, and one click sends a model straight to PrusaSlicer. Accounts are invitation-only; access can be revoked with a global sign-out, every change lands in an audit trail that cannot be edited, and the same tickets are exposed over a JSON API documented in OpenAPI 3.1 with a Swagger console.
