I love this model but with some poses the model becomes unbalanced and topples over. This simple “Hand Stand” serves as a baseplate to keep the model upright.

(I've only printed the right hand personally, so I have not been able to test the one for the left hand. Please post/comment if you're able to do so)

Get the rest of the hand from the original designer https://www.printables.com/model/677986-poseable-articulated-hand-model or the arranged plate https://makerworld.com/en/models/120129#profileId-139964
