Biqu B1 filament sensor strain reliever
thingiverse
**Changelog:** **v1.1:** Made the filament hole slightly bigger after I realized the filament would get stuck when trying to change it. <hr> After printing for a while with the Biqu B1, I noticed the filament had started to cut a groove into the filament sensor, so I decided to design a strain reliever for it. It also helps lead the filament through the sensor in a straight line. You will need: 1x M6 PTFE Coupler 1x Small piece of PTFE tubing You can use a knife or a screwdriver to round up the intake hole of the PTFE tube to make it easier to feed in the filament.
