MP Mini filament runout sensor holder

Remixed the side part to hold a filament runout sensor and a filter.
I use the little screw filter from EyeWolfDesign's Filament Filter/Sensor V2 at https://www.thingiverse.com/thing:2840455
I had to increase the filter by 1-2% for it to screw down tight.

I bought the sensor from Aliexpress, just search for "3D Printer Filament Break Detection Module"; I'm sure you can find the same sensor elsewhere.
