A sturdy platform on which to mount hardware inside your New Bright Razer (or RazerBuggy). Attaches firmly with eight screws and gives you a nice, solid place on which to screw H-bridges, a Raspberry Pi, FPV towers, or whatever else you may want to put into the thing. Fit is fantastic. Goes nicely with the New Bright Razer Buggy Servo Steering Mod: http://www.thingiverse.com/thing:652366.
