Custom Top railclip assembly for Ender 3 Neo and LED Bar from amazon. LED Bar available from Amazon here. https://www.amazon.co.uk/gp/product/B09KLJT6NM/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1 The Clip holds the LED Bar in place to ensure Ender 3 Bed is illuminated. My first design from Bottom Up and Print worked as well as could have expected. Tip, if like me you have a tool Assy holder at one end you could increase the middle post between rail and LED Holder thickness to accomodate but my was fine.
