Husqvarna 5-series pressure test caps design

[LittleTree]

Hi everyone, has anyone on the site ever made a design of some caps to pressure/vac test husky 5-series saws? I could be able to 3d print some caps from a design, but I have no idea about where to find some. I tried to make some 562 caps from scratch metal, but It Is kinda a pain in the arse and now that i Need some for the 550 Mark 1 and 2 i should build another set. If a design does exist, getting a 3d print would be much easier.
