Having tried similar things, I cannot stress enough how much you want to be printing molds like this in TPU unless you really really want your mold to be permanently embedded in the concrete

You can also print the object and use it to make a silicone mold, right? That doesn't stick to concrete.

True, but silicone is 10-20x the price of TPU
