Ender 3 Filament Runout Switch

thingiverse

This is partly my own design and a remix as I have used part of the Ender 3 filament guide by Jonasen, thanks! The filament run-out switch I bought (see below) did not fit so I designed a case that fits the Ender 3 Z-axis, using only the switch and wiring. Search Amazon - SIENOC 1.75mm 3D Filament Detection Module Filament Run-out Pause Detecting Monitor Sensor For 3D Printer Lerdge Board It does involve the removal of the Z-axis hex bolts (be careful not to lose the metal washers on top of brass component as they will be loose until you put hex bolts back through, I placed the small hex key that came with the Ender 3 through the hole to keep it in place) and roller wheel bolt to fit, but it re-uses all of them. Assembly is simple, slot the small piece in first and fit whole unit to your printer then place run-out switch into lid component and fit to base. This did not take to long to print and so if you choose to use it please do post your makes, any issues just leave a comment.
