I printed the Cable guide made by JayMake, it came out really nice, however it turns out I only have a 47mm and 35mm hole saw, so I made this one for the 35mm saw. It is just over 34mm diameter and so is a really nice fit. I tweaked the basic sizes but it is pretty much a copy.
The thread pitch is 2.5mm and is a standard ISO thread.
It's printed in black PLA on the Hictop CR-10.
Note I have designed this with plenty of clearance on the thread so it shouldn't be necessary to alter the sizing in the print settings for it to fit.
Prima Vlaue PLA
The thread clearance is built in so should work really well and is designed for the Ikea Lack table.
