Filament Sensor Housing
thingiverse
Created for an Ender 3 v2. It might work on other models, but I don't know about which ones are similar so download on your own risk. Below is an Amazon link on the specific sensor I bought: https://www.amazon.com/dp/B08QJDSZCL?psc=1&ref=ppx_yo2_dt_b_product_details You might need to reconfigure your firmware. Apparently, the switches have two positions: HIGH LOW Jyers firmware is default to LOW. This caused the switch to work opposite as it was intended. It would pause prints with filament in the sensor and run while it was empty. Just change FIL_RUNOUT_STATE to HIGH or opposite of whatever your setting is if you have the same issue as me and retest.
