Prepare to face the full might of Half-Pint Li'l Trapjaw Skeletor's Dim-witted but Cunning Chief Mechanic. It's hard to believe that he's the brains behind many of Skeletor's villainous inventions, even harder when he's so little and cute.
The model is designed to use 6x2mm magnets to attach and rotate the arms, head, and feet. Two magnets in each the neck and the head, and one for all the other sockets.
I find that the best way to arrange the magnets is so that all the magnets are oriented in a hierarchy so that all the pieces will attach to larger pieces. Orient all magnets on the base facing the same direction, then gue magnets into the feet, head, and arms, by pressing them down onto a stack of magnets attached to the base ones.
I've included a pre-supported and hollowed Lychee file for easier resin printing.
