The Original Dragon Egg - New & Improved for 2025

Please note: The print profiles “150% Scaled Egg” and “260% …” use out-of-date versions of the files. Please use the print profile titled “Designer's Choice…”

It's the original threaded dragon egg, great for Easter egg hunts, gifts, and Game of Thrones fans. This is my made-from-scratch design from 2022 that has since taken the internet by storm. (Cracker Barrel is even selling them!) As always, it's free to download and sell. I just ask that you credit me if you sell it or make a remix, as the Creative Commons - Share Alike - Attribution license requires. 

Update: March 2025. I've been working hard on a major redesign, and here it is!

Improvements include:

• Now in three sizes that nest!
• A hard stop on the threads so the two halves line up perfectly every time.
• Dragon scale texture on the inside of the egg. (Medium & large eggs only.)
• A fire symbol on the inside rim of the bottom half. 
• Improved scale texture with more nubs and imperfections. Every scale is a little different. 
• Three raised bands on the interior threads, so if the fit is too tight, you only have to sand the three banded areas. 
• My designer logo on the inside bottom to combat people sharing and selling this egg without attribution.

Stay tuned for a large and extra large version of this new and improved egg. Until then, this extra large version is the old design.

I highly recommend you use my print profile. I find that support helps the details print better on the lower part of the bottom half and a brim helps the top half stick to the bed, especially when printing with silk filaments. The details print better for me on my Bambu P1S when I print slow, but you can try incrementally increasing the speed. 

The vast majority of people will want to print the medium-sized egg (plate 1) or the large egg (plate 3). The small egg is on plate 2. 

I made every bit of this from scratch, including the scales. I made the scales by importing a custom texture into a Blender brush and placing every scale one at a time, adjusting the size as I went. I designed it with Sketchup, Blender, Fusion 360, and Meshmixer. (And Gimp for the scale alpha.)

If you find this model useful, feel free to buy me a coffee. 

You may sells PRINTS of this design, but you MAY NOT sell the digital files or share them on any repository. If you want to see them on a particular repository, message me, and I will add them myself. When you sell prints, please respect the Creative Commons - Attribution - Share Alike license and credit me on the sales page with a link to this page. Attribution is mandatory. 

If you make a remix of this or sell it, you may not remove the Yblood artist logo.

If the threads feel tight, try screwing the halves in and out repeatedly. I also find that the threads contract a little after a day or so. If that doesn't work, you can print again with an altered Horizontal Expansion / XY Compensation.
