hello, how did this hold up since you print it?

I have printed with PETG and have already used it a few times so far, everything is great, I have glued the holders to the base with glue, the disadvantage is that I always have to push them into the C-rail from behind, but this is not a problem.
Greetings Gerhard

really good idea. the pipe available here have an external diameter of 48mm (for 28mm pipe) Could you make a version for this diameter please. What is the gap between the external diameter of the pipe and the cutting Aid diameter ? thanks

I have added an STL file for outer diameter 48mm
