Single units


Models of this type are also automatically listed in: single-sheet

Pages dedicated to single units: a unit by itself is a single-sheet model, but is most usefult for building modular origami (multi-sheet) models. Having a separate page for a unit is especially useful for versatile units which can each be used to build a huge number of different shapes. A unit’s dedicated page contains all general information about the unit and links to the unit’s folding instructions when available.

This page lists models of a single type. You might be interested in folding instructions instead.
