Slice it. Send it. Nail it.
Prepare, slice and control your 3D printers. On your own devices.
Nozzle It All is a free, open-source family of apps for your phone, your computer and your browser. Each one slices on the device in front of you and talks to your printers directly, at home or through a private connection you choose. Your printer traffic never passes through a Nozzle It All server. No account. No analytics.
Android Active In invite-only closed testing on Google Play. Not yet publicly available.

What it does
Slice on your phone
An on-device slicing engine turns STL, 3MF and OBJ files into G-code, with a 3D plate, support painting and a layer-by-layer preview. Nothing is uploaded to a cloud slicer.
Control from anywhere
At home over Wi-Fi or away over mobile data, monitor temperatures and progress, start, pause and cancel prints, browse files and use the camera. Connect through Tailscale (recommended), Cloudflare Tunnel, OctoEverywhere or another private route you manage. Set up remote access.
Print in more than one colour
Slice multi-colour models for the U1's four toolheads, CANVAS, Bambu AMS, Prusa MMU3 and XL, Creality CFS, Anycubic ACE, Flashforge IFS, Qidi Box and Klipper filament changers, with a wipe tower and purge amounts worked out from the colours you have loaded. Tested on real printers so far: the U1 and the Centauri Carbon with CANVAS. See the test results.
Find something to print
Browse free models from MyMiniFactory inside the app. The designer's credit is saved with every project you start from a model.
Alerts when it matters
Optional background notifications when a print finishes, fails or a printer goes offline. Off until you turn them on.
Works with
Made first for the Snapmaker U1 with PAXX firmware. PAXX works entirely on your own network: no Snapmaker account, no cloud and no internet connection needed. Stock-firmware U1 printers are supported separately, and that support never gets in the way of PAXX.
Some printer types are confirmed on real hardware and others are built from the vendors' published protocols. The printers page and the app say which is which, and we do not claim more than we have tested.
Verified on hardware Klipper / Moonraker, Snapmaker U1 with PAXX firmware, Elegoo Centauri Carbon on OpenCentauri COSMOS (with CANVAS)
Not yet tested on a real printer Bambu Lab (LAN mode), OctoPrint, PrusaLink, Snapmaker U1 (stock firmware), and, in the next update, Elegoo on Elegoo firmware, Creality and Flashforge
Printer owners test Nozzle It All on their own machines with the app's Test Mode; accepted results are on the compatibility page.
Your printers stay yours
No account. No analytics. No ads. The Android app talks to your printers directly over your own network, and to MyMiniFactory when you browse models. It sends nothing to us, except a hardware-test report that an invited tester chooses to send, and there is no Nozzle It All account or cloud service behind it. Nozzle It All for Desktop and Nozzle It All Web, both in development, are built the same way: they slice on your device and talk to your printers directly. Read the privacy policy.
One family: Android, Desktop and Web
Android is in closed testing today. Nozzle It All for Desktop (Linux first) and Nozzle It All Web, the whole app in your browser, are built and being tested and aren't available yet. Windows is planned; iOS and macOS are deferred.
Android Active

Linux desktop In development
Nozzle It All for Desktop on Linux is built and being tested. Not yet available to download.
Web app In development
Nozzle It All Web, the full app in your browser, is built and being tested. Not yet available to open.
Windows desktop Planned
Planned after Linux. The Desktop app is being built so the same app can be packaged for Windows.
iOS Deferred
