I bought an o-ring but it's too thick. If I try to screw the top of the solo it will never screw, it's like it's going to have the thread striped :(
I saw the video and the o-ring is the same, don't know what to do now :shrug:
A Wychwood with voltage control like the E-Nano would be awesome! I know you can use a regulated power supply, but having it stock would be a lot better :)
