Grid placement (Movement) not working as intended

My placement function isn’t behaving as intended and I’m not well-versed with maths:

  1. Is slightly hovering
  2. It’s like it’s shifting completely. From the start of XZ Corner, it doesn’t go right to the edge, it just stops at the last increment for X-axis and for Z-axis it stops at 3 studs away to the end, on the opposite corner it goes out of the grid by several studs.
		local MRay = Mouse.UnitRay
		local RayResult = workspace:Raycast(MRay.Origin, MRay.Direction.unit * MaxPlaceDistance, RetrieveParams(Model))
		if RayResult then
			--
			LOWER_X_BOUND = Plot.Position.X - (Plot.Size.X*0.5) 
			UPPER_X_BOUND = Plot.Position.X + (Plot.Size.X*0.5) - Model.PrimaryPart.Size.Z
			LOWER_Z_BOUND = Plot.Position.Z - (Plot.Size.Z*0.5)	
			UPPER_Z_BOUND = Plot.Position.Z + (Plot.Size.Z*0.5) - Model.PrimaryPart.Size.X
			--
			local EndPos = RayResult.Position + (RayResult.Normal * (Model.PrimaryPart.Size*.5))
			--
			local posX = clamp(tonumber(EndPos.X), LOWER_X_BOUND, UPPER_X_BOUND)
			local posZ = clamp(tonumber(EndPos.Z), LOWER_Z_BOUND, UPPER_Z_BOUND)
			--
			Model:SetPrimaryPartCFrame(CFrame.new(SnapTo(posX),SnapTo(tonumber(EndPos.Y)),SnapTo(posZ)))
		end

Could someone point out where I’m going wrong with this? (It’s sandbox-type grid placement)

Does it happen on every corner? It may be an error in calculation of boundaries

If you watch the clips you can see how the behaviour is with every boundary of the grid. that’s the error I’m trying to figure out along with the fact it’s slightly hovering by like 0.5 studs
