Broken Honeycomb Cube

This was a CAD challenge to make 3D honeycomb infill pattern for SLA printing. I have these cubes with my contact information bossed on the top and use them as 3D printed business cards (at 40% scale).

This will print VERY nicely on a Form2 with the bottom (side with diamond holes) laid flat against the build platform then rotated 60deg around X axis. Disable internal supports!! The let Preform generate default supports

The rotation around X is critical to not have to use internal supports. Preform will complain but TRUST me, it prints just fine. Scale 30-100% to your taste!

It will PROBABLY print fine on FDM as well (not tested), but I recommend sizes 60-100% due to very small internal features TONS of retractions.
