Flyingbear Tornado DuetWifi electronics box

This box needed to mount DuetWifi on Flyingbear Tornado.
It uses original holes on back leg to mount (same on front leg used for original MKS Gen-L + GLCD box).
Initially i wanted to mount electronics near with PSU, but wires to head is too short
(cannot understand how it should be enough to go to front panel).

I made mounting plate from PET-G, cover from SBS.

Mounting plate have hole for 80-mm fan, it is not required (Duet worked well with passive cooling). But i decided to reuse fan from original box, to reduce noise i setup controllable fan2 output to turn on fan, if CPU temp more than 40°C (or any TMC gives overheat flag).

M106 P2 I0 T40 F500 H100:101:102 ; FAN2 - electronics cooler (use on/off, too noisy in PWM mode)
```

I think that honeycomb pattern done not optimal, but i'm still novice in Fusion 360.
