1/10 scale 3D printed Receiver box. This box works great to relocate your receiver from you slider to up by the servo.  This box works great with any crawler that has a dual servo mount as this box can be bolted right in that area.  Works great on Element and VS-410 crawlers.
Inside of the box is 43mm L x 28mm W x  32mm D and fits most 1/10 receivers. 
Box is not water proof but can help keep the elements out (waterproof receiver recommended for driving in wet areas).
