This is a model I made last year when i was learning 3D design. I use a lot of sticky notes in my work and I'm kind of a nerd, so when i was working on a Gelatinous cube dice holder box, this just happened.

Very simple design. No Supports needed. I add a little fuzzy skin to give it texture. Feel free to turn that off. I used some iBoss transparent green PLA+ for my model. But the transparency aspect never really came to be. I hope you enjoy!
