Filament Cutter Box with backstop

Filement Cutter Box with a backstop to reduce filament waste. I’ve also added small lines on the sides which touch the cutter to increase friction and ensure that the cutter doesn’t fall off. Print without supports, with the opening upwards. This works together with the filament cutter designed by Pomi: https://www.prusaprinters.org/prints/67509-filament-cutter-45deg
