Update 10/26/19 - Continue this piece at https://www.thingiverse.com/thing:3938275, where I reduced size for simplicity's sake. Update 1: New files added with a 21.4mm outer diameter to fit printing tolerances better. My testing showed that the slots for O-rings are a bit tight, so I'll update those when I have time. I might also shorten the entire assembly. An adapter insert for the Rival D.Va blaster that should provide an air-tight fit for your preferred barrel material. The design features a 21.75mm outer diameter and a 16.2mm inner diameter, with slots designed around #13 O-rings but suitable for any O-ring greater than 11/16" ID and less than 3/32" thick. Not tested yet. This adapter should fit smoothly down the barrel until it hits the grate in front of the plunger. It also works with the Kronos, and probably functions better when the AR is removed.
