To reduce the altitude bearing stiction of my Hadley telescope, I created these bearing rings that use PTFE tubes as an interface material.

The reduced stiction will require a well balanced telescope and possibly a spring to put more pressure on the bearing.

Built around standard 4mm OD, 2mm ID (4x2) PTFE tubes. These are cut to ~17mm length.
The Tube holders are fastened to the insides of the bearing interfaces. 
 

My print settings:

PLA

4 walls, 20% infill

(PTFE_holder has to be printed on side, using standard supports to ensure strength of rod)

Hardware:

4 - M4 nuts (+1/side for spring)

4 - M4x12 bolts (min length)



Enjoy!
