I made a modification of the standard watchX housing design. It has bridges on top and bottom parts and snap locks, which will stick together both parts. Attention: This design is made for Onyx 3D-Printers (https://markforged.com) with a nylon/carbon fiber material mix. This material is stiff enough that the snap locks will not break. Download link:

You can download 4 files: Bottom part with bridges, button, top part with bridges and snaps and top part with bridges, but without snaps.
These are the modifications:
- Reduced diameter (3%) of the pins on bottom part for better lock.
- Bridges on both parts, snaps (hooks) on top part. The noses of the snaps are oversized. Take a rasp and
shorten them, till they snap and lock easy. - Enlarged button height to avoid gap.
Be careful when you try to close the parts first time to avoid OLED display damage. Adjust it with a rasp or a knife. My Onyx made version locks nice. I made no tests with other materials.
