Filament Extruder Detector Interlock for the Lulzbot Mini

thingiverse

I'm adding a small modification to the Filament Extruder Detector v3 by flipper: http://www.thingiverse.com/thing:454584. During intense printing, the toolhead shakes rapidly, causing the sensor difficulty in getting an accurate reading of the filament diameter. To fix this, I decided to securely attach the sensor to the toolhead. This attachment piece fits snugly into the holes where the locking bolts are located on top of the Lulzbot Mini Extruder v2 toolhead (https://www.lulzbot.com/store/tool-heads/lulzbot-mini-tool-head-v2). The results showed a significant improvement in measurements for me, and I'm hoping it will help you too! Keep in mind that this modification does not add more than 1cm to the distance between the extruder and the sensor.
