Printed CORNERS for the hexagonal shelf we had on Prague Maker Fair 2018.
We used it to display printed models.
10x10x160mm Aluminium sticks are used for prisms. Prisms are secured by hot glue sticks (of course, what else...). All the prisms are the same lenght - you can shorter them as well as extend them.
All the spheres are assembled together with zip-ties (of course, what else...)
