I have been searching for a mod that would allow me to craft Unbreakable items and make my own recipes for a long time now.
There is several mods I've found but they all have problems and none of them are in a useable state.
The best mod I've found is called Personalized Recipes Mod but it is long abandoned. The mod does allow me to place modded items with NBT tags and enchantments in the crafting output GUI, so it does exactly what I want it to do, it does not however save any recipes I make, so after quitting the single player world all the recipes are gone.
The mod is opensource so if anyone would be able to fix the save bug or make any changes that would make the mod useable I would be very greatful (or make a new mod alltogether).
