Egg Candler Attachment for Flashlight

thingiverse

This little cup attachment boosts the performance of cheap flashlights found at Harbor Freight and Tractor Supply, making it easier to candle eggs. We've successfully candled quail eggs with this design, and as printed, it performs fairly well. Future improvements could include applying a layer of Sugru around the top for added durability - specifically, the skin-friendly version available here: http://amzn.to/2GF2oa5. I printed the attachment with supports, but I believe it would hold up just fine without them. To remove the small lip of molten plastic from the bottom, I used a knife to scrape away the excess material. Fortunately, this didn't affect the fit, which is snug at an inner diameter of 26mm.
