BoxForge is a free, browser-based parametric packaging generator built specifically for FDM 3D printing. Enter your dimensions, pick a style, and get a print-ready dieline in seconds — no CAD software required.
A smarter way to design custom packaging for your 3D printer.
BoxForge takes the guesswork out of designing folding cartons and box nets for FDM 3D printing. Instead of wrestling with CAD files or measuring by hand, you simply enter the dimensions you need, choose a structural style, and BoxForge instantly generates a validated net layout scaled precisely to your printer's build plate.
Whether you're printing gift boxes, product packaging, storage inserts, or custom enclosures, BoxForge handles the geometry so you can focus on the design. Add your own logo, choose a filament colour, apply a pattern fill, and download a clean SVG ready to slice or laser cut.
Enter length, width, and height in millimetres. BoxForge validates everything against your chosen printer's build plate in real time.
Straight tuck, reverse tuck, internal divider, and a two-piece lid & base — all generated as flat nets ready for printing.
Upload your own logo or use the default. Apply pattern fills and occasion overlays to personalise every box.
Select your exact printer model from a built-in database. BoxForge constrains the net to fit within your real build volume.
Work out the true cost of each print — filament, electricity, machine wear, and markup — all in one place.
Browse hundreds of filament colours from leading manufacturers to find the perfect match for your project.
Everything you need is on the main designer page.
