thingiverse
This is a simple Filament Runout Sensor Design I came up with for my Voron printers. It uses a left-over microswitch, a magnet and a 10mm ball bearing ball. To built this switch you need: KW10 Micro switch ( https://s.click.aliexpress.com/e/_dSOAZLK ) 10x4mm round magnet disc 10mm ball bearing ball 2x 2.3x12mm plastite screw 2x M3 Screws + T-Slot Nuts to mount it to the Frame PTFE Tube Update 2020_08_20 I added slotted holes to mount the micro-switch to fine-tune the actuation point.
