Smartrapcore BMG Aero mount

Didn't like no existing designs to motor-mount a direct extruder of a usual kind to a (8mm rod version) smartrapcore (alu but it doesn't matter) so i've decided to do a nice rigid carriage for my "bmg aero" (Trianglelab's hybrid, not really a clone).
Loosely based on seemingly good [8mm carriage by ryandgarrison](https://www.thingiverse.com/thing:1953419) because i'm too lazy to bother re-doing something that's already good.
Also huge thanks to RaptorHunter for his [this](https://www.thingiverse.com/thing:4226245)


The result is pretty heavy, at least the way i printed it with massive wall count, but also it's deadly rigid. Smartrapcore itself is too weak to allow decent speeds anyway, as even reinforced bed wobbles badly if you try to go fast.

Keep in mind i don't use original endstop arrangement, that's why there's an adjustable trigger on the back side. There's an alternative STL included with a mounting hole i found in original carriage whatever it does.
