About
Foldy 3D turns 3D models into papercraft you build with your own hands. Pick a model, print its paper template at true size on your home printer, then cut, fold and glue it into a real 3D paper model, step by step. Handmade crafts make a relaxing new hobby to enjoy on your own or as a family project.
HOW IT WORKS
▸ Pick a model. Browse the catalog, spin any model in 3D and choose how tall you want it.
▸ Print. Foldy 3D unfolds the model into flat paper pieces with glue tabs, numbered seams and fold lines, and creates a PDF that prints at true size (1:1) on Letter or A4 paper.
▸ Cut, fold and glue. The build guide walks you through every piece: cut it out, watch the fold in a 3D animation, glue the tabs and attach the piece to your model.
WHAT'S INSIDE
● True-size printing on Letter or A4, so every piece fits the next one.
● Color printing on one side or both. With one-sided printing, seam numbers sit on the glue tabs and fold lines are a shade darker or lighter than the face, so the model looks clean; with two-sided printing, the full-color design goes on the front, and fold lines and numbers go on the back.
● Two-sided printing works with a duplex printer, or you can flip the stack and feed it through again by hand.
● A printer check page with a 100 mm square shows whether your printer scales the page, and an alignment page helps the two sides line up.
● A step-by-step 3D build guide with animated folds.
● Your progress is saved, so you can build a model over several sessions.
THE CATALOG
Start with the Retro Rocket, the Jack-o'-Lantern and the Bat: all three are free. The Skull, an anatomy model, comes with Foldy 3D Pro. New models are added to the catalog without an app update.
GOOD TO KNOW
● All you need is an ordinary home printer, paper, scissors and glue. No 3D printer required.
● The catalog downloads over the internet the first time you open it.
● Browsing the catalog, spinning models in 3D and choosing a size are free for everyone.

What's New in Foldy 3D
1.0.1
October 27, 2026
• New: watch the 3D building animation in full screen. Tap the arrows button under the model, and tap the model to hide or show the buttons. • Look at your model from every side: the camera now turns all the way to straight above and straight below. • Big models got lighter: with hundreds of pieces the step and sheet bars no longer run off the screen, and the last step — the one that joins the parts — opens right away and uses far less memory.
