This is a Battery tray for the Traxxas TRX-4, allowing you to mount & secure a 5000mAh battery up front over the motor & front wheel wells. You'll just need 4 screws & a velcro strap. I designed in some removable supports so you shouldn't have any issue printing it. It printed well on my Maker Select V2.
Added some pics of the forward mount battery tray on my TRX-4, It was designed with the 2 cell 5800mAh LiPo battery that I have, in mind. And a pic with the mock hood on over the battery and battery tray.
