tevo tarantula y carriage - Remixed

Hello. Thing received version two. Link below
[Link to version 2 of this part](https://www.thingiverse.com/thing:2730391)

I remixed it after print original.
Reason: When I print thing I use PLA, and small parts(columns) are broken in print progress, also broken after print(where i mount belts).
I use screws for fixed it, and do this remix.

Changes:
Carriage bed:
- More stronger and easy-to-print: less bridges, may print on high-speed.
- Part of bracket included:no broke in bel
