This on has some sort of expansion sleeve covering it, a litte more advanced than what I've been looking at. I'll have to find it on the web, but you can 3d print the 2 moulds to make this. It's pneumatically driven silicone balloons basically. It's not too complex, silicone and wax, you pour it. The first mould is a wax mould that gets inserted into the secondary mold for silicone. When it's dry, you melt the wax out and you have 3 internal um, balloons, that operate via air. Would take some digital proportional air valves to drive it, and an air compressor of course. Blew my mind when I seen one in motion as well. I don't know why I want it, but I do!
