A "The Other Half" backplate for Jolla phones. A slightly modified version of the design from the Developer Kit
For more details, check out the website.
This is an experimental design with altered latches to improve the attachment to the phone. The test prints have worked well for me, but please bear in mind it's still under development.
Please get in touch if you'd like any of the other designs using this new latch configuration.
The original design, which I'm hoping this will eventually replace, is still available.
