My sister-in-law’s sunglasses lost an accent from one of the earpieces, leaving the left temple loose. Could I fix this?, she asked. Twenty minutes and 63 millimeters of plastic filament later, my purchase of an Orion Delta 3D printer was 100% validated.

The accent on the print bed.

The accent installed.

With the temple opened.

And the other side, with the original accent, for comparison. I later painted the printed accent gold with some nail polish, and you could hardly tell the difference between the two.

If you happen to have this same pair of sunglasses, and your pair has also lost one or more of its accents, you can download the 3D models and print a replacement yourself.
