Foldrivo

Turn a sheet of paper into something useful with Foldrivo, an offline workshop for designing small paper boxes. DESIGN A BOX AROUND YOUR IDEA Create an open tray, an open-ended paper sleeve, or a tray with a separate lid. Set the length, width, depth and glue-tab size in millimetres or inches. Adjust lid clearance to suit your paper. SEE THE PLAN BEFORE YOU PRINT A live unfolded preview shows the outline and fold lines as you edit. Solid lines mark cuts; dashed lines mark folds. For lidded trays, switch between the base and lid previews. PRINT AT ACTUAL SIZE Export a vector PDF for A4 or US Letter paper using the Android document picker. Each net gets its own page, automatically rotated when needed. Foldrivo checks whether the design fits the selected paper and includes a 50 mm calibration ruler. Print at 100% or Actual size and check the ruler before cutting. KEEP A PERSONAL WORKSHOP Save up to 200 designs locally, reopen them for adjustments, and continue your last draft. Delete individual designs or clear all local designs and the draft from settings. Exported PDFs remain in the location you choose. MAKE WITH CONFIDENCE Follow the included cutting, scoring and assembly guide. Choose light mode, dark mode or your device theme. PRIVATE AND OFFLINE No account, ads, analytics or cloud database. The app works without an internet connection and requests no network or dangerous permissions. You control where exported PDFs are saved. Designed for thin paper and light cardstock. Dimensions are nominal; paper thickness and printer settings affect the final fit. Make a sample before your final assembly. Large designs that do not fit a single sheet must be reduced; tiled printing is not included.
