How to make a local grouped model that follows you?

I need to have a grouped model that only the local player can see follow the player while they move. It looks like this: https://ibb.co/1QP43mX The player needs to always be in the middle of this model, and no other players must see it.

Please help I have tried a lot. I would appreciate a bit of help :) I am beginner!

EDIT: Script I have so far (not working at all, nothing happens):

player = game.Players.LocalPlayer
character = player.Character
hmndrootpart = character:FindFirstChild("HumanoidRootPart")

while true do
    local playerPos = Vector3.new()
    game.Workspace.Table.PrimaryPart:MoveTo(hmndrootpart.Position.X, hmndrootpart.Position.Y, hmndrootpart.Position.Z)
    wait()
end
