Had some issues in the past that PTFE tubes got damaged by the edges of panels if the holes in the panels were tight fit.
These passthoughs were my solution against this. If others had the same issue you're welcome ;)
For people who have clearance issues with the threads I also included the 2nd Nut versions which are slightly bigger on the thread and therefore should fit better. But the best fit always depends on the print settings and the printer. Therefore i would recommend to try out the normal ones first since too much play also doesn't help.
