Even better standalone mod for Tevo Tornado

#Even better standalone mod for Tevo Tornado

This is full redesign of my "better standalone mod for Tevo Tornado": https://www.thingiverse.com/thing:3023832. It still greatly reduces the dimensions of printer, improves cooling and making the wiring more neat. But this new version improves a lot of things:

- lower and upper part is designed to be screwed together. Much more durable and looks better
- Now it supports both MKS Gen L and MKS Base boards.
- Boards is located on the outer part
