Rotate cube by 45 degrees on all axis

[RoiEX]

So I have the following Problem:
I'm trying to rotate a cube by 45 degrees in all directions, so that with a second cube that is rotated 90 degrees further it forms a nice star-like shape
I tried doing that using the 1 key, however the shapes only align at the bottom, they are slightly offset at the top which is noticeable because the textures don't align exactly.

I even tried hacking the cubik format to check if it's just a value that I could change, but apparently it's more difficult than that (at least I got around the compression) ^^

Any help on this is much appreciated

Minecraft doesn't support that sort of rotation, so neither does Cubik.

If you were making a model for something other than normal Minecraft json models you could disable that limtation in Edit > Model Properties > Restrict Rotations.

Unfortunately I already disabled that option.
My problem is that the rotated cube isn't perfectly aligned, just off a couple of pixels.
