This part snaps into place on the Storm Racing Drone for routing antennas to a preferable configuration for reception. The antenna tubes pictured are Traxxas antenna tubes (TRX1726). One cut in half is long enough but I ordered two in order to have two caps. I didn't like the support material generated by my slicer so I added some to the model. It can easily be cut off once the print is complete. The piece snaps over the top plate and the antenna wires feed through. Clean up the holes for the antenna tubes with a 1/8" drill bit.
