A dragon egg I designed. This is big enough to fit Pilotz's Ice Dragon and kimseungwoo11's Flame Dragon (https://www.thingiverse.com/thing:5390184, https://www.thingiverse.com/thing:5337105) without scaling up.

Print the top and bottom as separate pieces, with the top nose-down. Depending on your printer capability, you may need some supports for the upside-down top to print the first few centimeters correctly. I raft the top, but no supports or adhesion should be needed for the bottom. Other printer settings are whatever works best for your setup.

Please do not steal or sell my design. It's free for personal use, so enjoy!

Happy printing!
