Day 12/30 ✏️ Fidget Pencil | Sliding Articulated Toy

Day 12 of my September Challenge is here! ✏️

For today’s release, I designed something a little different - a Fidget Pencil!

At first glance, it looks like a chunky stylized pencil, but slide it open and it reveals multiple connected sections that can move around and be played with. When you’re finished, simply slide everything back together and it transforms back into a pencil again. ✏️✨

It’s a simple concept, but surprisingly satisfying to open, move around, and close again - perfect as a desk toy, fidget, or just a fun little 3D print.

12 models down, 18 to go! 🚀
