DJI Phantom 2 h3-3d Gimbal clamp/ GoPro 3 lens cover

I was looking for a way to keep the h3-3d gimbal from swinging around and nothing was here. Here is attempt 1,its basic, but worked out pretty good with no additioan parts needed or supports.
I just posted version 2, this version still uses no additional parts or supports but might need rafts. CAM2.stl is version2
Version 3 has jusr been posted, this version will allow you to plug the USB into the GoPro without removing the gimbal clamp. Cam3.stl is version3.

If you are looking for the vision + version its here
