Hobbyplus Terranaut 8x8 Cargo Bed

Remixed a longer bed that wouldn't fit on a standard 220220250mm like the Ender 3
Print with supports flat as it would sit on the truck
*Added what I used for a flatbed, its remixed from the 3rd section of an RC semi
*Added a beta model with support tabs to properly support the flatbed - Work in progress part
*Updated to final version
