This will allow you to put a camera on the pipes of the Creality 3D printer Enclosure.
The poles are 16mm dia.

I have mounted, at different times, a Dlnk DCS-942L and a Dlink DCS-5020L pan and tilt and Blink mini Pan and Tilt cameras to my printer.

As it shows in the first picture, I normally have it slid all the way to the bottom of the frame pole. The platten can be installed with either side facing up to slightly change the height when the blink mini pan and tilt is used.

Because it is in two pieces you can also use a gopro mount to replace the platten part.

I have included the GoPro adapter. It is the red part in the photo.
I print it with the side down and have no problems.

If you are using a gopro mount you may have to print a second camera pole clip just to clip below the first camera pole clip to hold it up the pole as the clip will slide down.
This doesn't happen with the Dlink 5020 or the blink camera as they are quite tall and with the clip slid all the way down the pole, those cameras look onto the printer bed.

I added the screw to hold the camera on. It fits Dlink pan and tilt and Blink mini pan and tilt and probably many others as I think it is a standard camera mount size.
Screw B is about 1 mm shorter thread, just in case the original screw is bottoming out in the camera base. Screw C is about 2mm shorter.

I also added a pole clip, Clip w screw2. that can take a nut and bolt to clamp it to the pipe. The clamp is like a gopro item so it uses 5mm nuts and 25mm long bolt or gopro screw about 25mm long. I had to use it to hold the Dlink 942 up the pole.

If you need gopro type extension bars and stuff look at;

there are about 200 pages of remixes off of MoonCactus designs.
Mine is not a remix but I do use a couple of his extension bars.
