for: fixed = { -0.5, -0.5, 0.4375, 0.5, 0.5, 0.5 } you could do this to make it thinner instead i think its better fixed = {-0.5, -0.5, 0.496, 0.5, 0.5, 0.5} i made my own cover mod i needed it to cover some blocks also you can make a horizontal cover :D fixed = {-0.5, -0.5, -0.5, 0.5, -0.496, 0.5}
