I use the design from J-Hodgie and modify a bit to my USB camera. you may need a bit touch up to fit your USB camera.

1. Dowload the files from J-Hodgie first
2. Replace the bottom support by enclosed file. when you install the camera, a double side adhesive tape can help to fix the position easier.
3. change the top mount left and right, also add adhesive tape to secure the position.
4. Cut a bit excess part manually to avoid some plastic part blocked the camera.
