Isn’t this just a filament buffer? You can buy one on AliExpress for 10$
Link, because this is not what I think of when I hear filament buffer. This uses a motor to feed filament and it's a tool so you can use it on lots of machines with reverse Bowden tubes.
I just found this on AliExpress: $11.25 | Mellow LLL Filament Buffer For 3D Printers - Automatic Filament Feeding, Break Detection, Improve Print Quality For Voron Vzbot https://a.aliexpress.com/_mtdTiwv
Literally use one just like this to feed filament to the extruder - has feed and retract buttons and can also double as a filament runout switch as well
