Road Show multiball lock solenoid repair

Road Show multiball lock solenoid repair

Today I need to make this. Road Show pinball machine has a ball lock mechanism, where the locked balls are kept in a scoop and released one by one with a solenoid.
This got stuck and my investigation revealed the plastic part was now missing the collar that prevents it from going too far. The collar also keeps the return spring in place.
This is AFAIK unique part to this game and as such I don't have it in stock. Unlike the Elvira's 3D printed bracket earlier that was a temporary fix, this one could be easily 3D printed and expected to last.
Nothing beats the sound of multi-ball - Adam's Family #pinball - in the morning... SHOWTIME!
