Transformers Earthspark - Mandroid (Hardtop) Arm

I've been meaning to post this for a while but waited til I could get it tested (thank you kieliah2) to make sure it works. The robot arms that come with the build-a-figure Mandroid are nice, but they have no articulation beyond the balljoint they use to connect to the figure. I made my best approximation of Hardtop's design, but added a balljoint elbow and a wrist swivel, aaand figured I'd also give an open hand option since the hand uses a 5mm peg.

The assembly is simple and shown in the second image, just using filament (or a 1.75mm pin for the shoulder joint pin, then gluing the shoulder armor and forearm onto the joint parts - you may wanna do the latter afterwards so that you can more easily add the pin.

If you wanna make another Hardtop arm, you just need to
