Most 3D-printable glasses cases will put your glasses at risk of scratching due to the nature of plastics and glass. This is a case that is sleek, print in place, portable, and very protective. This is a two-part-print with a hard shell that can be out of whatever plastic material you prefer (I use PETG) and a soft inner layer of TPU to protect from scuffs and scratches while also providing support to the glasses via a "nose bump" design. All of these features make the build stable, scalable, and safe. Disclaimer: I spray painted the case in the image above and due to my lack of skill got the paint a little dusty and blotchy. Anything that you think might relate to that sort of technical failure on my end is indeed 100% my fault.
