    A new name: WrenSlicer

    Text on parts, smoother corners and more printers

    • Raised and engraved text on any face of a designed part, sized to fit.
    • Rounded inside corners where features meet, for stronger, cleaner parts.
    • Wi-Fi printing for Creality, Flashforge and Anycubic printers now on iPhone too, plus six new budget printer profiles from Kingroon, Two Trees, Comgrow, Weedo and Longer.
    • An open-source licences screen and a clear note that WrenSlicer isn't made by any printer maker.

    A real 3D part designer and USB printing

    • True 3D solids in the part designer: tilted sketches, chamfers, fillets and flared edges.
    • Patterns: rows, grids and rings of holes, plus mirrored features.
    • Print over a USB cable from Windows and Mac to printers without Wi-Fi.
    • Wi-Fi printing for Creality OS printers (K1, K2, Hi, Ender-3 V3 and more) and the Flashforge 5M and AD5X.
    • A smoother plate view on desktop that never drops frames while you move parts.

    The desktop app catches up with the iPhone

    • Trace a part from a photo, or draw your design and turn it into an editable part.
    • Print history with results, ratings, notes and "print again".
    • Calibration prints, an "Ask about materials" advisor and a multi-printer dashboard.
    • Alerts when a print finishes, stops or pauses; models open straight from a .zip.
    • Ironing, fuzzy skin and settings that change by height; magnets, nuts and pauses.
    • Built-in help, menus, recent files, full keyboard use and screen-reader support.
    • Behind the scenes: a G-code safety checker on every printer profile and hardened file readers.

    Ready for testers

    • The desktop app checks for updates and has Report a Problem built in.
    • Open models straight from Windows Explorer and the Mac Finder.
    • Over thirty reliability fixes: safer saves, recovery of damaged projects and settings, and a check that blocks sending G-code made for a different printer.
