    Yeah, you'll have to think of your own way to attach the motor, though

    Mine won't exactly be good, because I prefer to film it in one video, but it will be fine. When I cover the camera with my hand, that's path seperation.

    That doesn't matter.
    Please do the modification in Step 12 (I didn't add that as comment yet as i somehow can't edit ibles atm) that you use in that helix thingy instead of two yellow connectors only gold ones and wined the track all the way, I haven't tested that but that should make it work better. :)

    your welcome. no because me and the blue nullet made the final updates to my ball machine
