Gyroid

thingiverse

Two custom gyroids: one thickened right out of the box and the other cut with a spherical shape. Both were designed using Netfabb. I printed the cube using Cura on my DIY Hypercube, scaling it up by four times to ensure the walls weren't too thin for proper slicing. Alternatively, if you want to print it at a smaller size, consider using Cura's "surface special mode" - I discovered this workaround after printing the first one. Have fun!
