Step 15: Repeat Steps 1 to 14 and make total of 6 units.
Step 16: Now, if you've made the other modular origami on this site before www.origami-instructions.com , you'd know that assemble the units, often times we just insert the tips ito pockets.
This cube is no different. Each unit has 2 tips and 2 pockets. We'll utilize them to assemble the cube.
Starting with 2 units, insert one tip into one pocket.
Step 17: Now, take another unit and insert its tip into other pocket.
Step 18: Now just repeat Steps 16 and 17 to assemble the rest of the units.
and here's the completed origami modular heart cube!
