I was inspired to make this design because I couldn't set off fireworks last year 2021/2022
So i came up with the idea to recreate some bigger fireworks instead of the normal fireworks in minecraft.

This is just the start of a big Fireworks-Grid-World which I will update after I make a new creation.

I would recommend making this with the WorldEdit plugin. (Also possilble without WorldEdit)

This 3d Art is also possible to create in SURVIVAL MODE

• Build up minimal 40 blocks (minecraft:acacia_fence) (break one for one fence)
  

• Create the radius of the particles when standing on top of the fences with the next command:
      //hsphere minecraft:gray_stained_glass 24
  
  

• Make the explosion on top of the fences with minecraft:glowstone/minecraft:sea_lantern (see pictures)
  
  

• Build 1/4 __l of the particles of the fireworks (I used 3 different matching colors of terracotta/concrete)
  
  

• Replace the whole glass sphere in air by selecting a square of the outer corners
  with the next commands: //pos1
               //pos2
      //replace minecraft:gray_stained_glass air
  
  

• Complete the particles by selecting the 1/4 __l part of the fireworks
  with the next commands: //pos1
              //pos2
  Stand on top of the fences and
  type the next commands: //copy
               //rotate 90
               //paste -a
               //rotate 90
               //paste -a
               //rotate 90
               //paste -a

  Don't doubt and ask Chest.
