Like this one?
I've used this exact one before, best catch can I've used in terms of filtering the oil out. But they fill up super fast because the can is tiny. I switched to an ebay can with custom baffles and I rand through a bunch of different baffle setups till I get to something as effective as that one. And that basically involved getting a sintered brass filter (like in that aos) and using that as part of the baffle in my other one.
Other trouble with that design is that once the oil level gets up to the filter you start siphoning the oil into the intake. Other downside is that the can is acrylic which will eventually fail in the presence of gas and oil.
