My son used to always make these elaborate marble tracks out of random things in the house when he was a kid and would get so psyched whenever he made a successful track. Now it's my turn to make one. So stoked to give this a try. Thanks for sharing it!

I got an ad and you didn’t even get money for it, that’s very sad

awesome work! do you use supports for printing?

Just add a motor and it will run forever

What size marbles does it use?

how did you even print it so succesfully!??
