Introducing the QuackPack™My custom blocks. Requires Nuterra Block Injector Library.
QuackPack™, my block pack, individual block files and the Blender files for all blocks can be found in this link:
It is a block pack with all my blocks in it. If I remember correctly, the Block Injector can read zip files inside of a big folder now, so all you need to do is download the QuackPack™, unzip it, then move it into the Custom Blocks folder to use it.
Inside the Mega Drive link are also folders containing the individual block folders and the Blender files for all of them, if you wish to use them.
