Shields for the Transformers Optimal Optimus Vintage figure, modeled after the TransArt version (wich is downscaled from the original) and pictures. They fit perfectly into the forearms, with pegs for assembling. They can be also be put on the shoulders, where they stand, but with a gap (as shown in pics) and can form a barrier (like the ones in the cartoon).

The file of the shields contains the pieces for one forearm. You need to mirror it to print the other.

UPDATE 07/06/2020: I'm adding the files to print poseable hands for this figure. They're not show accurate (I think the original design makes the fingers too thin), but they retain the thumb capability to be turn to the other side for the beast form (the hand is symmetrical, so this design doesn't need to be mirrored in order to print the other hand, just like the original ones) and each phalanx is articulated. You would need some wire pieces to attach the fingers to the hand and one for the wrist joint.

UPDATE 05/06/2021: The shield parts file was edited after a user detected some issues with his printing application.
