Taranis Q X7 LiIon 18650 battery holder Remix

This is my remix of [curly_cz's](https://www.thingiverse.com/curly_cz) great [Taranis Q X7 LiIon 18650 battery holder](https://www.thingiverse.com/thing:2260923). I removed all horizontal fillets as my printer frequently makes a mess of them when printing at low resolutions. I also removed the supports in the XT60 holder so my slicer software can add its own and removed the nut recesses and adjusted the screw holes for self tappers. Also made the wedge a single piece.
