Steam Controller shoulder bumper mechanism
thingiverse
EDIT: It seems that Steam has released STL file for this part a sometime ago with name "trigger mount". At last! I wonder when did they release it. It seems that my version of it has become useless. I had to repair shoulder bumper mechanism, but one that was already in Thingiverse didn't feel right and didn't keep spring in place well, so I made this with measurements taken from unbroken bumper mechanism. I wonder why Steam never shared the official 3D file for this one. People say that this part should be printed with some strong material like PC, but so far PLA has been working fine for three months and I can always print a new part if the current one breaks down.
