While Googling images of walker MOCs for inspiration I found this older post by @DarthTwoShedsJackson showing their build:
Naturally, it wasn't wobbly, I mean poseable enough for my tastes, so I made some modifications with ball joints and changed a few details.
It can be put into some nice dynamic poses now, although you have to be really careful doing so. Only time will tell if the click hinges are going to be bent due to the angled positions. Anyway, hope you like what I did with your design!
