Ring type tripod head for Canon 100-400mm F5.6-8

I DO NOT TAKE ANY RESPONSIBILITY OF BREAKAGE OR DAMAGE TO YOUR CAMERA

That said, i suggest you print it in PETG or any stronger material with 30%+ infill, as mentioned if it brakes and brakes your camera i do not take responsibility. I used 0.16mm layer height.

The print requires supports, and I recommend printing with a brim.

It is a tight fit so i suggest you put something inbetween the tripod head and the camera, i put a fabric and it doesn't scratch the lens but if you don't put anything it might scratch the lens.

If you have big hands it maybe hard to change the zoom, your hand might bump in to the lower part of the head.

I added a hole under the head so that, if you wish (as I did), you can screw a standard tripod head onto the 3D-printed head.

You will need two screws, i suggest you first print the tripod head and then search for the screws, how long they are it doesn't matter, what matter most is the diameter.
The screws you will need are:

A tiny one long 12mm with a diameter of about 4.7mm

and a long one, long 15mm+ with a diameter of about 4.2
