Change the “UTADiameter” parameter with the diameter of your telescope tube for it to fit your tube.
I tested this for diameters from 4" to 25", so it should work for any telescope tube in between. I use this same adapter on my 10" telescope, with a tube diameter of 11.75". The adapter holds my 2lb eyepieces without any issues.
Printed flat side down with 2 simple tree supports for the bearing recesses.
