>>10297166I'm designing an action figure myself. Scale is 6 inches, all parts are 3D printed. I'm aiming for revoltech range of motion but with minimal sculpt breakage.
Pic related is a test. I'm holding the shoulder joint to the torso using my fingers because there's no torso socket yet. There are two way to move the shoulder joint around: with the deltoid tucked in, and deltoid on top.
The range of motion is quite large. You can even move the hand behind the back like in a handcuffed position, or over the torso to the other shoulder, or over to the opposite side like drawing a sword, or even behind the head like drawing a sword from the top.
The sculpt is a muscular build. For a thinner build the range of motion will be even greater.
The elbow joint is an early design. I improved it since.
