Replacement Smartcartridge housing for Vanmoof S2

This may be used as a replacement for the Vanmoof S2s Smart-Cartridge housing in case yours is broken or split apart. Or it might be used with your own DIY controller for the bike, now that VM is no longer. 

I've omitted the internal structure as in screw-terminals and mountpoints, so you can add your own mounts for custom controller boards. 

Also I've removed the simcard-slot and microusb accessible from the outside, to make it a little harder for would be thieves to just remove the simcard.
