This 3D-printable egg Candler is designed to make checking egg development simple, clean, and effective. Originally sized for guinea fowl eggs, it also works perfectly for standard chicken eggs, making it a versatile tool for smallholders, backyard poultry keepers, and hobby breeders.

The Candler fits over a flashlight/torch to block stray light and focus illumination directly through the egg, allowing you to clearly see fertility, vein development, and embryo growth during incubation.

Printing Notes

• Prints without supports
• PLA or PETG recommended
