PTFE tube mounting, suitable for aluminum extrusion 2020.
M10 PTFE screw. Mounting screws for aluminum extrusion - M3x8
The bottom hole has a diameter of 5 mm so that the PTFE tube can fit into it to prevent the filament from rubbing against the mounting.
So let's introduce PTFE from the top through the M10 screw holding the PTFE, and push the pipe all the way to the bottom until it protrudes slightly or is even with the bottom hole :)
To obtain the highest resistance to cracking when screwing M10, I recommend printing in portrait orientation with a 5mm hole to the table.
