Aloha from Hawaii!
Here’s my first try with inlays and this type of living hinge design. To create, I used the Inkspace elliptical box generator (https://www.instructables.com/id/Generating-elliptical-boxes-using-a-laser-cutter-a/) to create a 240mm x 120mm x 20mm box with a “lid” angle of 179.9 degrees. In doing so, this created an elliptical box with dimensions that can still fit inside the Glowforge, though close to maxing it out. The lid then became the upper half of the frame border and the frame looked symetrical. Everything came together quite snugly when accounting for the depth of the Proofgrade material, requiring very little glue.
The turtle/honu tribal inlay was CAM’ed out via Fusion360. So far, I’ve made three of these but am most pleased with how the Proofgrade cherry and basswood inlay designs both came out. I did another on non-proofgrade birch plywood where I stained the living hinge and the honu inlay and then coated everything with poly. It also turned out well, but it was SO much easier to go with Proofgrade where no finish work was required. For each, medium draftboard with a simple hole for hanging was used as the backing.
Happy to hear thoughts or recommendations for improvement.
