Morserino-32 Pocket Travel Case – Slim, Rugged, Rubber-Band Closure

I wanted a case for my Morserino-32 Pocket that added almost no bulk, so I could just throw it in my bag or luggage and not think about it. My main use is taking it on the motorcycle, where there's a lot of road vibration, so it had to be rugged. The Morserino sits snugly in the base and barely moves inside the case. Why rubber bands? I spent a fair bit of time on clips, lids and latching mechanisms. Despite my best efforts, I kept coming back to the tried-and-tested rubber band. Two bands hold the lid and base together, and they come with a couple of bonuses: - A bit of grip against whatever surface it's sitting on

- A little isolation from that surface, which helps with vibration

Better ideas welcome If you've got a cleaner way to close it and do away with the rubber bands, I'd genuinely love to hear it. Post a remix or drop a comment. Looking for a lighter cover instead? Willi OE1WKL has his own flexible TPU protective cover for the M32 Pocket, which is great if you just want to protect the face of the device: https://www.thingiverse.com/thing:7268262 What's included - Base and lid (STL)
