Transformers G1 Sandstorm

Here we have 2 different size arms for G1 Sandstorm. They work like a G1 seeker and fit snug over the existing arm. You will need to print one and then print a second using the Mirror option. Please see the pictures. I do not know if the original gun will fit in the hand as i do not have one. I am trying to create one, but my skills are still Novice
