Anycubic Vyper Extruder Roller Filament Guide

thingiverse

I have my filament spools hanging above my printer, so it was pulling upward fairly hard on the runout sensor. I had done a similar print for my Ender 3, so I redid it for this. Friction fits onto the bracket for one of the Z-axis rollers. The dimensions in relation to the runout sensor aren't perfect, since I got tired of reprinting it due to it being hard to measure, but they're pretty close. I used a 635 bearing for mine, so I included a sleeve and shaft for that. The shaft diameter will probably need tweaked; I had printed mine on my Ender 3 before I upgraded, so the accuracy on that print wasn't great, but I reused that print for this and didn't change the model. You'll want the shaft diameter such that you need to press the shaft into the bearing with a vise or something, so that the bearing doesn't slide around. The shaft should snap in to the bracket without too much pressure. I recommend printing the bearing sleeve with as small layers as possible to get the upper curve nice without supports; I did mine in 0.06mm.
