Casting Pressure pot recommendations?

Not 100% sure if this will fit the size requirements, Rybonator on youtube
makes resin dice sets and casts with a modified pressure pot from harbor freight. Link to info in video

 

I want to also point out when looking for your pressure pot you want to make sure that it's trustworthy. PSI Should at least be able to get to 20 to 30, and the bolts shouldn't be too difficult to tighten down. I've heard stories of people slicing their hands up from trying to tighten poor quality bolts. And also, not having a pressure pot explode on you is important hahaha
