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

Wow! In step 3, part 8, it looks exactly like an optical illusion!

Maybe it IS one... :P:P:P

do you have a video

No, sorry. Maybe you could make one?

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. :)
