This is a PETG 3D printed roof rack for the RC4WD Mojave or Tamiya Toyota single cab hard bodies. This is the PLASTIC version, the METAL version is available on the product page. This version is light weight but less durable that the metal version, but has all the same features. 
 
It has adjustable cross-bars with holes in them for mounting scale items, and includes lightbar mounting tabs for 5" lightbars. I have an optional LED lightbar available. 
 
2mm and 2.5mm hardware included. You will need to drill (4) holes in your cab to mount it.
