Slightly relaxed tolerances to compensate for thermal expansion of the material
Round holes for the side ports
Redesigned front cover with cutouts for buttons, display, and ports
Recommendations:
Print in a light-colored material to mitigate heating when exposed to sunlight. The first version of this case was printed in black and expanded due to sunlight and tightened around the Omni 20 making it very difficult to remove. This version has increased inner tolerances to prevent this.
Cut a piece of tissue paper and wrap it around the bottom of the Omni 20 to act as a soft inner lining to protect the finish.
Cut out a clear piece of plastic (blister packaging can be a good source) and glue to inside of cover to protect buttons and display.
