tevo tarantula y carriage - Remixed v2

Version two. More stronger parts
I remixed thing again. From my remixed carrige and remixes of remixed things.
Also i compound with [this part](https://www.thingiverse.com/thing:2601244) and made like a [this part](https://www.thingiverse.com/thing:2596846), for a less supports need.
Reason: I need more stronger construction and connection for legs.

Changes v2:
Carriage bed:
- More stronger connection for legs. Need some force to connecting now
- Fix for less supports need, like i
