Two gyroids: one just thickened out-of-the-box. Ther other cutted with a sphere. Both designed with Netfabb.

I've printed the cube with Cura on my DIY Hypercube, with a 4x scale. Otherwise the wall was too thin to be well sliced by Cura. It you want to print it really small, a workaround could be to use the "surface special mode" on Cura (I found this option after printing the first).

Enjoy!
