Armor Stand Display is used to showcase the armor set. You can use any kind of armor you want to display.
This guide will tell you the method to design an Armor Stand Display in the Minecraft game.
First, you need to dig two blocks on the ground and place 2 blocks of redstone in it. Then place two redstone lamps at the top of redstone blocks.
After this, you have to place two armor stands at the top of redstone lamps. Add a full set of diamond armor on both of the armor stands.
The next thing you need to do is to push glass blocks blocks into the armor stands. Place for pistons on the front and four glass blocks in between the pistons and armor stands, as shown in the image below.
Push these pistons by using redstone blocks and add smooth quartz slabs at the top and dark oak trap doors on all the sides of redstone lamps.
You have successfully designed an Armor Stand Display.
