Introduction: Knex Ball Machine: Nebula

I'm proud to present to you, my first Knex ball machine, Nebula!

This project has "been in the works" for more than a year, but realistically only 2-3 months of that was actual construction. In the end, I decided not to finish paths 5 & 6, for a couple reasons. Since the path separator was on the far left side of the machine, there was not a lot of room to continue the two remaining paths. I also didn't the motivation to finish the paths, so I decided to leave them unfinished.

The piece count came to 10,817 pieces, but if you'd like more specific data I've made this spreadsheet accessible to anyone who has the link: Nebula Piece Count.

I don't plan on making instructions for any of the new elements found in the machine, mostly because I've already disassembled the entire machine. Hopefully the pictures provide a decent idea of how they work, but feel free to ask any questions in the comments.

I uploaded the video in glorious 1080p for all of you to enjoy, the song used in the video is "The Mystery Spot" by Bassnectar and G. Jones.

There were a couple kinks I had to work out, but it went pretty smoothly. Thanks!
