What if Apple designed a sci-fi face mask? Guess it would look like this. Rear part has 4 belt holes. Size: 199 * 265.5 * 198 Verticles: 193,102 If you have a print bed under 250mm, there is a cut version attached, which consists of 5 separate parts. Cutting line coincides with geometry, so feel free to print separately and assemble with ease. Lenses and black parts should be printed separately and then glued from the inside. For the lenses you should use SLA/DLP printer and black toned transparent photopolymer.
