No problems printing file. Had to grind down some high spots so marble could roll.
Lots of fun even for seniors
Great for every one
Well designed and prints easily.
Definitely worth it
These are all fantastic designs and they work great!
My daughter loves it
Printed and deployed to production aka my daughter playground. She is using it right now with a mix o marbles and small spheric bells like the ones you add to a cat collar. Everybody is happy here! We like it!
