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
bPrintValue.Value = game.ReplicatedStorage.RaftParts.Foundation.Object.Model
local blueprint = bPrintValue.Value:Clone()

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

--animTrack.KeyframeReached:Connect(function(kf)
--  if kf == "Stop" then
--      playingAnim = false
--  end
--end)

script.Parent.Blueprint:GetPropertyChangedSignal("Value"):Connect(function()
    print("ERROR?")
    if bPrintValue.Value then
        blueprint:Destroy()
        blueprint = bPrintValue.Value:Clone()
        blueprint.Parent = workspace.CurrentCamera
        m.TargetFilter = blueprint
    else
        game.Players.LocalPlayer:Kick("Blueprint Error. Please Rejoin\n\nData did save")
    end

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