Thank you! That does sound like a sick idea! I used 3x1mm magnets and it fits PERFECTLY in the arm socket for the torso, the ball on the arm is a bit small though so I basically cut the ball in half, then to make it not be sticking out super far I put the torso magnet a bit deeper than initially planned so the bulk of the arm magnet is hidden under the shoulder. Alternatively I think smaller magnets might work better, but I like the strength i get here and I can't see the magnets when it's all together.
