Pikachu made of 3D Pixels or Voxels.
I think it took about half a dozen redesigns until all the voxels were sorted.
Voxels are turned 45 degrees to get them printed without support.
This was my first voxel project and more are already in the making.
WARNING: This is only for the 3D Printing Heros! Don't try if you are on novice level.
A collection of designs using Voxel Art is available here
Printed with PLA at low speed.
