This is a slightly improved version of the Dyson Trigger Lock, created by fabi.swob on Makerworld. This model features a removed portion of the top, allowing for a ball to slide in between two different locking positions.

The reason for adding this feature allows for the trigger to fully lock open, or fully lock closed. Which makes the trigger more effective when being used. I.e. you can set it to on, and it stays on.

I hope you find this useful like my wife does!
