I don't know what would be
optimal, however in a couple of the small scale #Rotor style exprimental blocks I've made I've used 3mm holes with I think 1.5mm spacing.
Here is an example (part of my old pump-block mod) of what you can do if you take to the hole grid with a hand power drill at an extreme angle using a 3mm drill bit. It takes a fair bit of practice and control to keep the drill where you want it, but you can end up with a Cathar esque block using only drills
