We had a fun request from one of our members for a tiny Christmas tree keychain,so we took the idea way further and turned it into a super satisfying flexi bubble-pop fidget tree!Every ornament is a little button you can press with a little POP sound, flip it over… and keep popping forever.Perfect pocket-size sensory toy for kids & adults, wiggly flexi body, stress-relief fidget. ✨

For the first few pops it takes a bit more strength to "break in", but after that, the buttons pop in very easily! Tested with popping it throughout the whole day, and it still feels as satisfying as in the beginning!

What’s inside the release:• Flexi Bubble Pop Xmas Tree – pocket fidget + keychain version• Single-color / 3-color / 4-color print options• With star topper + without star topper• Support-free, fast print, fun to carry!

I dont normally comment on anything but this team is the best at releases. I may not print everything you release but there is always a ton of stuff to print. You always amaze me with your releases. Thank you!

SEREV3d

Thank you for the kind words! I feel like the more our community grows, the more we're inspired to cater for all the needs at 3d printing, we can expand a bit more, and spend more time and effort into bringing diverse fun releases on the "plate" 😊

I printed the tree right away, and I LOVE it! Please tell me you will have more "bubble pop" items in the future!

Crystal Woodmancy

These printed AWESOME! Thy definitely won't last long when I show them off!

SEREV3d

Hahah, glad to hear! We're planning to do a few more of these designs, fitting for different styles and occasions 😊

SEREV3d

Yes!! We're thinking to do a cute monster head with popping eyes (maybe one side with a smiling face, other side with a grumpy face) And a few different tiny bushes, and trees with popping fruits, (fruits with seeds), and a funny but quite gross idea, is a little pocket zit/blackheads popper haha. Also if you have any more specific idea, let us know, there are lots of fun possibilities with this design! 😊

What about a bubble pop key - for a play on the word keyring? Or staying with the flexi theme, a star with articulated points and a bubble to pop in the center and each point.
