Placing system is offset by a few studs?

Hello! I have been trying to replicate the placing system from the game Raft and it works, but the object is offset by a few studs

My Placing: https://i.imgur.com/tCenwu9.png

Raft's Placing: https://i.imgur.com/aQQeHOe.png

I'm ONLY asking about the placing, not anything else

My Client Sided Code:

wait()
print("RUNNING")
local m = game.Players.LocalPlayer:GetMouse()
local rotateAmount = 1.5707963267949 -- 90 degree rotation
--local looseRotationAmount = 0.00017453292519943 -- 0.01 (very small rotation) (For Misc Item Placement)
local turnDegress = rotateAmount
local cframe

m.KeyDown:Connect(function(k)
	print(k)
	if k == "r" then
		if turnDegress > 6.2 then
			turnDegress = 0
		end
		turnDegress = turnDegress + rotateAmount
	end
end)

function roundBy7x7Grid(cf)
	local x,y,z = cf.X,cf.Y,cf.Z
	return (CFrame.new(x-(x%7),y-(y%7),z-(z%7)))
end

--[[
	
	Okay, so, for now, I'm just using the "Foundation" blueprint
	I will use a different blueprint but this one is just for testing purposes

local bPrintValue = script.Parent.Blueprint

local blueprint = bPrintValue.Value:Clone()
blueprint.Parent = workspace.CurrentCamera

--local animTrack = game.Players.LocalPlayer.Character.Humanoid:LoadAnimation(script.Parent.Swing)
local playingAnim = false

	end
end)

local down = false

If you need the server code, ask me and I'll update the message
