The World's Smallest Infinity Cube – Challenge Accepted!

When @austinvojta set the bar with a 9.2mm tall infinity cube printed with a standard 0.4mm nozzle, beating my ordinary smallest version which is 10mm. I couldn't resist the challenge. So here it is—the tiniest print-in-place infinity cube ever at just 7mm tall! Not only did I shrink it down, but I also made it lighter—his version weighs 6g, while mine comes in at a featherweight 2.3g. Who says size matters?

Why This Cube is Wild:

• Ultra-Tiny: At just 7mm, it’s the smallest infinity cube out there!
• Super Lightweight: Weighing in at just 2.3g, it practically floats.
• Still Functional! Despite its tiny size, it flips and folds just like the big ones.

Printing Instructions – Read This or Cry Later!

This is a torture test for your printer. To pull it off, you need:
✅ The built-in profile – seriously, don’t skip this.
✅ If the quick 0.2mm layer profile does not work, try the slower 0.08mm layer profile.
✅ A well-calibrated printer – every micron counts!
✅ High-quality, dry filament – any moisture and your cube might weld itself shut. Use regular PLA, do not print with silk - it will not work!

Post-Print Tips – Unlock the Magic!

• Let it cool completely before touching it—moving it while warm can fuse the joints.
• First movement requires care! Gently work the joints loose by hand.
• Use pliers if needed—gripping each section lightly can help free up tight spots without breaking the cube.
• There's the smallest 7mm version, but if you struggle with that try the 8mm version, still tiny but easier to print.
