For my Voron 2.4 I've made a passthrough and strain relief for a bowden in the top panel.
It uses an ECAS04 to fixate the bowden and 4x M3x4x5 heat inserts to fix them without nuts.
I don't remember what bolts I've used, probably M3x8.
I've also included a drill for the mounting holes.
The author marked this model as their own original creation.
