Hello,
I cant help notice that models have a fixed scale and cannot be voxel modified. It could be an interesting mechanic to have a scale modifier that increases size of then model and the stats, so you can make tiny bots to run around conduits and repair your ship. The models are 3D and the scalar is 1D thus would have to scale to the cube to be realistic, with a linear loss function according to abs(original scale - scale) * balancingTweakingConstantScalar.
this would allow for quite interresting things like gigantic reactors, massive guns and tiny bots.
I hope you like that idea
