Shrink wrapped MagicShifter ;)
I worked very hard for many months to create the current 3D printed case for the MagicShifter and now it works quite well I have to say. It survives drops onto stone from 1.5m and protects the LEDs and the sensors from dust and splash water.
But t also has some drawbacks: You can't see the cute :) PCB design anymore and the status leds get dimmed by the case... So overflo had this brilliant idea to use shrink wrap as a minimal case for the shifters.
If you decide to use this kind of "case" you have to protect your shifter a little bit more than if you use the hard 3D printed case but it looks just awesome :)
