Cardboard Icosahedron with Interlocking Tabs


Here’s a project for the cardboard boxes languishing in your recycle bin. It’s a bit tricky to get the last 5 panels attached to the rest although this seemed to be the best tab design of the 3 I tried. Have fun adding your own cut out or engrave patterns to the sides. Hope you enjoy!



Here are the other 2 tab designs in case you wanted to play with them. Version 1 makes beautiful perfectly aligned and strong connections but takes a lot of work to weave the tabs together.

This design can also be used to make octahedrons and tetrahedrons I think. I haven’t tried to align all the tabs, but I don’t see why it wouldn’t work. Nice design.


You could make this by inny or outie:
