It is as I said. It looks like there is no screw hole to put the screw back in its place and the part itself doesnt come of too. Trying to fix that "engineering masterpiece" for longer than a hour and yes one screw sabotaged me.
With wood I've used parts of a toothpick to get screws to stick if I ruin the threads. There might be some options, I bought a 3-Doodler that can extruded plasic, you could shoot some in the hole and insert the screw or you might be able to get some rod and do it with heat. Have you seen the guys that buy polypropylene tarps and make things with them, they heat the plastic and use it for repairs, it melts like hot glue. If the thread is self-threading, it kind of looks like it is, the part didn't have a hole to begin with, during assembly it was pushed through creating a threaded hole, these have a high tendency to strip over time.
I don't think I broke anything. There are taps holding it but it looks like it is impossible to get it out without breaking the tabs. And in the service manual it just says to remove the screw.
