Switch Joycon dual angle customizable support bracket

This is a remix of https://www.thingiverse.com/thing:2194717 - the original didn't include print supports (and I didn't include them in the slicer), and I wanted to be able to tweak angles. There's also scope to change thickness of the printed part and how broad those beams are that make up the whole thing

Customizable to set the thickness of the bracket, the angles for the supports and optionally include print supports

The included .stl is the defaults as I see them.

Updated: 22nd May
* Added configuration of total length (default now at 130mm to give better clearance for a charge cable)
* Set default for Supports to Off (Slic3r didn't bridge the perimter correctly, YMMV)
* Made Support for the bridge at 1.5mm instead of 0.5 to try and give the slicer a fighting chance
* Reduced the gap in the Joycon rail keyway (1.2mm was a bit on the loose side, but still gave an acceptable hold on initial print)
