I love the filament Guide by Abernus but I snapped off the threads twice while mounting, so i made the thread thicker and the hole a little smaller to guide the filament better.
I have not managed to break this screw yet :D
The author remixed this model.
I made the thread and the nut larger and at the same time made the hole for the filament smaller (~2mm) to guide it more precisely to the PTFE tube.
