Made a model stand for my dad for his iron man POP figure or whatever those are, but it could work for other models.

the peg is about 3mm wide, i made mine out of a metal rod actually but you can either print this one or make one yourself in that same shape and angle and it should work great, just make sure to print it pretty solid otherwise your model may break it off due to layer line direction etc.

base is 3 inches long
