Command for 1.9/1.10 versions : https://minecraftcommand.science/commands/45582
This command adds a way to create custom crafters that let you craft saddles, horse armours, bedrock, barrier blocks, and so much more. It will also be reused in some of my other command block contraptions in order to create the special items they add.
Info about this command and its installation can be found here : Link to the video
