STARSTACK

⭐ STARSTACK — The 5-Piece Interlocking Star Puzzle

Print it. Break it. Stack it back together. 🧩✨

Five colorful pieces. Three layers. One perfect six-pointed star. STARSTACK looks simple when it's assembled, but once you take it apart, getting it back together is a real brain-teaser. Every piece reaches across two layers and locks into its neighbors, so you can't just lay it out flat like a jigsaw. You have to work out which piece goes where, in what order, and which way up. 🤔

And the best part for makers: 🚫 NO SUPPORTS NEEDED. Every single piece prints flat on the bed: no overhangs, no cleanup, no scars.

✨ Highlights

• 🧩 A real 3D puzzle: 5 interlocking pieces across 3 layers, and each piece is a unique shape.
• 🚫 Zero supports: each piece is designed so that every layer sits on the one below it.
• 🎯 Tuned fit: 0.3 mm clearance between pieces. Snug, yet it goes together by hand without forcing.
• 🌈 Made for color: print each piece in a different filament for a stunning rainbow star.
• 📦 Print-ready STLs: already oriented and laid out, so just slice and go.
• 🎁 Great gift and desk toy: it looks great on a shelf and keeps fidgety hands busy.

🧠 The Challenge

Difficulty: ●●●●○ (Medium–Hard)

• Every piece spans two layers, so no layer can be built on its own.
• Pieces must go in one at a time, in the right order.
• 🤫 Hint: not every piece is printed the way it's meant to be played…

Quick to learn, satisfying to crack. Hand it to a friend and time them! ⏱️😄
