Ender 3 S1 Filament Sensor Mount

thingiverse

My printer is in a tight spot and I needed something to hold just the filament sensor. Since the filament spool is inside the cabinet, the part that I remixed this from didn't work well because the filament would need to bend too far and it would cause too much frication on the cabinet door which would make it difficult for the print head to pull the filament. I modified the part I remixed this from to move the filament sensor more towards the back of the printer. It is also shorter and has 3 large slots in the walls to reduce print time and save on filament (two of the slots have an extra little cut-out in it so that it can print without supports). Since the filament would be routed between the top extrusion bar and the top belt, I added a filament guide to make sure the filament does not rub on the belts as it moves. The filament sensor still has enough freedom to move from side to side (see picture) however it does reduce the build height by a small amount.
