Ingenious! Nice work, Zimmy! 
Now for your next project, find an assortment of cases that match either the width or the height of the L5, and have holes lining up with at least one of the L5’s camera, buttons, ports, or SIM tray, then slice them all up and glue them together to make one good one. 
Bonus points if they’re all the same color!
P.S. I totally agree about flexible vs. rigid cases.
