The Universal Egg – Defined by Perfect Formula

The Universal Egg – Defined by Perfect Formula 🥚✨This is not just any egg. This is the egg—modeled from a mathematically defined “universal egg formula” and translated into Fusion360 with precision.Each egg is printed in two pieces with a clean, scarf-seamed Z-seam, practically invisible from the outside. They screw together with low-friction threads using a clever tube method instead of traditional thread operations. Once it's closed, it’s closed—no accidental pop-offs!🎨 We used Soleyin Ultra PLA pastel filament for that ultimate Easter vibe—but feel free to experiment!🖨️ Print Settings• Nozzle: 0.4mm• Layer Height: 0.20 mm• Infill Density: 15% TDMS• Nozzle Temp: 220°C• Bed Temp: 50°C• Material: Soleyin Ultra PLA• Supports: Not needed• Skirt: 5 loops 2mm from Base of Egg (to stabilize bottom layer and help with cooling)• Cooling Fan: Enabled at 100%• Wall Line Count: 3 (non-negotiable for inner/outer/inner and scarf seam)• Z-Seam Alignment: Scarf Seam🛠️ AssemblyJust remove from the plate and screw the two halves together! Done!Optional: Add fuzzy skin to the outer shell using slicer modifiers for texture (avoid thread area).💡 Why This Egg?We saw a lot of egg containers out there, but none that were free, mathematically perfect, seamless, and fun to open. So… we made one! And now you can print as many as you want and brighten someone’s Easter with the perfect egg.Happy printing and Happy Easter from Iron3Dad! 🐣****🛠️ Edit – Additional File Added🛠️****Hey everyone! I’ve added a new variation titled “Cloud Slicer” for anyone using the Creality Cloud slicer. This version has the top and bottom placed side-by-side to avoid confusion.The original .STL and .3MF versions show the egg halves stacked vertically (as seen in the preview). If you're using the Cloud slicer, it may merge them into a single object. That’s a known quirk with the web-based slicer—not a broken file.✅ If you download the files and open them in a desktop slicer like Creality Print, Orca, or Cura, they’
