Want to make a floating item that never despawns? well. This command does that! this allows you to make a item display! no armorstands either! (those are way harder to work with) Change the "id:glass" to whatever block you want like "id:iron_block" to customize it. to get rid of item burn it with flint and steel or do /kill @e[type=Item] to get rid of it. but this command may delete other floating items, so it is recommended to use flint and steel. have fun with this command!
