This is a simple bowden tube holder and runout sensor with the Voron logo. It replaces the original bowden tube holder.
The sensor is a micro switch. The model also needs JST connectors, four M2x10mm self tapping screws and some cables. A little piece of bowden tube is needed too.
See the github page for build instructions.
After printing I noticed my micro switch was a bit smaller than the one the model was designed for which was very good because I was out of M2 screws as well. Instead I taped the switch in place with some M3 VHB tape on both sides of it. That worked fine and held the model together.
I use Ellis' Klipper configuration. I connected the switch to an end stop pin and ground. The Normally Open (NO) side of the micro switch is used so with filament loaded it will shorten the pin to ground. I configured the pin to use internal pull up and be inverted (^! before the pin name in Klipper) for it to work. If something goes wrong with the cabling, it will complain filament is missing and I can fix the filament sensor before I get an actual run out.
