Runout Filament Sensor Holder

I bought this [Runout Filament Sensor](https://www.aliexpress.com/item/32965114166.html?spm=a2g0o.order_list.order_list_main.54.20e41802FC3UPQ) and made this holder that can be placed right before the extruder. Mine is a little taller because I am using this [Dual Gear Extruder](https://www.aliexpress.com/item/1005003217848048.html?spm=a2g0o.order_list.order_list_main.68.20e41802wWnZjA), so won't fit perfectly for the stock extruder for Ender 3.

# Version 1

In this first version, I made it because I didn't have a screw so long that can go through the part + sensor. So I use:
- 2 screws m3x16mm (top)
- 2 hex spacers m3x8mm
- 2 screws m3x8mm (bottom)

# Version 2

In this second version, I bought a longer screw. So I use:
- 2 screws m3x30mm
- 2 nuts m3
