Hollow dice

The hollow dice I've designed in Blender and afterwards printed in resin using a 3D printer Anycubic Photon S. The file with "x6" in name (and without “FDM”) contains the 6 dices with supports for resin printing, the file without “x6” - just a pure single dice. The file with “x6” and “FDM” in name contains just 6 dices.
