Filament Guide and runout sensor

I decided to move the runout sensor on my printer to the end of the filament arm. Originally I had mounted it close to the extruder but it made filament changes harder. This waste a little more filament but it is easier to deal with.

The sensor is a stock piece I picked up a pack of 5 from Amazon.(https://www.amazon.com/gp/product/B01CS82B8K/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1)

UPDATE: Added a new version that allows you to install a piece of tubing in the ends to help gui
