Knikkerpot (marbles hole?)

Designed this 'knikkerpot' in Tinkercad for my son. I guess the english word would be 'marbles hole'?

Easy to print and it works just fine. Playing is really fun and challenging. Push the marble too hard and it will shoot over. Too soft and it'll roll back off. :o)

Please let me know what you think of it and when you printed it! Enjoy!
