A simple mount for the filament run out sensor that incorporates a fitting for a reverse bowden tube. Remix of a model by natronics on thingiverse to alllow mounting it to an arm or post or 2020 extrusion directly. I also made the mounting holes smaller for M3 heat set inserts. I used this arm: https://www.printables.com/model/487507-mak-sovol-sv06-sensor-arm-mod The sensor came with my Biqu B1 but they are a common cheap sensor. The mounting holes are 20mm apart. Here is a sensor that fits from AliExpress: https://www.aliexpress.com/item/32917462715.html?spm=a2g0o.productlist.main.1.20a9q4PXq4PXCk&algo_pvid=2100d236-51c3-4c83-b129-503823b4dc14&algo_exp_id=2100d236-51c3-4c83-b129-503823b4dc14-0&pdp_ext_f=%7B%22order%22%3A%22531%22%2C%22eval%22%3A%221%22%7D&pdp_npi=4%40dis%21NOK%2128.57%2127.42%21%21%212.49%212.39%21%402103847817402948846305396e708f%2166054980628%21sea%21NO%212738264576%21X&curPageLogUid=6sjKHTukHGeB&utparam-url=scene%3Asearch%7Cquery_from%3A

The author remixed this model.
Made the sensor mounting holes a bit smaller to accommodate M3 heat set inserts and put a hole in the middle to attach it to an arm from the 2020 extrusion on the top of the frame.
