Updated shock holder

The shock holder I found the holes are to big they were about 21mm now they are 13.5mm. updated it for my friend to fit his shocks for the traxxas slash shocks and his sprint car. If you already printed the other one out I added a cap the can be placed in to the larger hole make it fit more standard shocks. the shock holder has areas to place the shock upside down to drain out.
