Been spending a lot of time with Qubicle Voxel Editor lately and have decided to make my own versions of the Minecraft tools and weapons in voxel form. Here is my take on the diamond set.
These models are not in any resource pack or addon, yet. As soon as I have models for all four tiers (yes there are 5, not 4. People always forget gold) I will make a resource pack "addon" that will use these models.
