This is really fun to play and fidget with, with a unique fun sound. It's very difficult to snap apart, so I have not done it much, not too sure how durable that part is. But, it's almost addictive to use.Cool fidget toy, my three year old liked it. Good gift as part of a gift bag. Don’t understand what 3d printed means though. Would have bought whether 3d printed or not.The sound is so satisfying. The feeling of the toy is pretty cool. I saw these on TikTok and I knew my kids would love them.
