***FEATURED IN KEYNOTES MAGAZINE*** Create and print master key systems in an instant with Master It. Master It is perfect for small or on-the-fly systems. Create a master key matrix immediately with zero math and zero worries of cross-keying. Either enter in your own TMK or tap Randomize to create a complete master key system containing a single TMK, a single sub master, and up to 64 change keys. Each output delivers a fixed sub master and set of change keys. Master It is built to create a system immediately to print and keep in your records at your shop. It is capable of saving and reloading one project at a time. The goal with Master It is to create and AirPrint a system in an instant. If on the road when printing isn't available, email and save features are secondary backups prior to printing. Email is also ideal when a printer is not AirPrint compatible. Currently supports: Kwikset .023" Corbin Russwin .028" Weiser / Falcon .018" Ilco-Unican .018" Schlage .015" Arrow .014" Sargent .0125" & .020" Corbin .014" Obeys MACS rules for each selected system. AirPrint, Email, or Save any system created. Create 5 or 6 pin systems. Randomize feature to always generate a completely random TMK every time. Use the two filters to restrict the TMK to only shallow depths, or to always include the shallowest and deepest cuts. Tap anywhere on the matrix to select or deselect a bitting for the key chart. Shake your iDevice to lock the primary functions on the main screen. This is to prevent unwanted changes (i.e. accidentally tapping Reset). To unlock, just shake again. All change keys can be individually identified. Use the Project Name / Keyway box for temporary saving information. The actual printout will allow you to write in the business name, personal name, address, keyway, and phone number conveniently. After printing, the system can be continued manually on paper. Additionally, you can tap on each change key to display the pinning. Compatibility: All iPhone, iPad, iPod Touch types and generations with a minimum iOS version of 12.0 Found a bug?

3D GO – 3D Printing, STL Viewer & Slicer 3D GO is a fast, all-in-one 3D printing app for finding, previewing, organizing, and slicing 3D models from the biggest sites in the world. Instead of jumping between five different websites, folders, and slicers, you can do everything in one place. Search across Thingiverse, Printables, MakerWorld, Cults3D, Creality Cloud, Thangs, MyMiniFactory and Sketchfab at the same time to find STL files for parts, tools, upgrades, miniatures, home décor, and just about anything else you want to 3D print. Whether you’re printing functional parts or artistic models, 3D GO makes it easy to discover the best files from the entire 3D printing community. Select models with a full 3D preview and STL viewer, so you can rotate, zoom, and inspect it before you download or slice. This helps you avoid bad files, broken geometry, and wasted filament. You can also open any STL from your device and view it instantly inside the app. When you’re ready to print, 3D GO includes a built-in 3D slicer that converts STL files into print-ready G-code. You can prepare files for PLA, PETG, ABS, TPU, and more, then export them for your printer using your normal workflow. It works great alongside Bambu Studio, PrusaSlicer, Cura, and Klipper-based setups. You can save any model from any site and organize them into custom collections. Keep folders for different printers, materials, or projects, search through your saved models, and manage even huge STL libraries without losing track of anything. 3D GO also lets you explore what’s happening across the entire 3D printing world. Browse trending 3D models, check out design contests, and discover new creators without visiting each site individually. No matter what 3D printer you use — Bambu Lab, Prusa, Creality, Anycubic, Flashforge, Ultimaker, and more — 3D GO fits right into your workflow.
