Simple endoscope mount. Mounts a 7mm usb endoscope to a 30mm hotend fan.

10/26/17 Added Camera tube V2. with shorter arm which raises the camera off the bed more and gives a little higher view of the nozzle. Also added a bit of length to the tube to allow for a small zip tie. I found that over time the tube loosens up with the heat from the LEDs in the endoscope.
