I created an Addon Minecraft Bedrock, which allows Uncraftable armors. This works with all the armors of the game, including chainmail armors and tortoise carapces. I also add for fun the craft of the Nether portal and the End portal. I left you a screen of the End portal craft, so now it’s up to you to find that of the Nether portal (;
(index: chainmail)

Have fun !
