Simple BJD Eye With Hole for LED
These are simple 3D printable eyes with a hole in them so you can insert an LED and make light up dolls' eyes.
I've designed them for Dollfie Dream 1:3 scale vinyl dolls but they should fit SmartDolls and other 1:3 scale dolls.
The hole is designed to fit the typical 3mm LEDs found in electronics starter kits. The hole is a tight fit so once the LED has been slotted into place it will be extremely difficult to remove it again.
Disclaimer: if you attach other electronics and stuff to your dolls don't damage them (and be wary of heat).
