Yes, absolutely. We actually love printing 3D designs and 3D scans made by people around the world - this is why we developed Looking Glass.
Custom Looking Glasses are listed as a Pro level reward, $99 (early bird) and $120 (regular) - you'll receive both a Small and a Medium Looking Glass of your designs/scans.
Keep in mind that we can only accept 3D models in OBJ format for this reward level. All backers at this level will receive an upload link after the Kickstarter is complete.
