You’ll need to snap a selfie and a side profile of your face and send it to Funky 3D Faces. Within two weeks, the seller will turn them into a 3D model and print it into a 15mm head that’s compatible with all Lego minifigures. If you fancy a new look, you can also ask for a different hair style or color.
From the sample images, it looks like the heads do bear some resemblance to their owners. But they do seem to suffer a bit from the washed-out look and lack of detail seen in most 3D-printed products today.
Still, they’d likely make for a nifty gift for the Lego fan in your life, or a fun addition to your own collection. Each head costs $30 and ships worldwide.
