I’ve seen quite a few of these 3D printed cinema lens housings over the last few years. We’ve featured some of them here on DIYP and I’ve even designed a couple of focus rings for my own lenses in the past. I’ve not had a go at printing a full housing, though.
They need a lot of plastic to make, and they look 3D printed. Are they really worth it? In this video, Adam Harig at FoxTailWhipz attempts to answer that question by printing one of the housings available for his Tokina 28-70mm f/2.6-2.8 lens.
