I liked the idea and found nothing alike on thingiverse. so i made this

EDIT: Some people are having issues with the cartridges falling out. i dont know why it works for some people and some dont. To avoid issues i added two test files. One is the normal size i used and one i made narrower so it wouldnt be loose. Maybe test it with them first, so you dont waste filament or time

I made this Video about it https://www.instagram.com/reel/CnNL-ZNDIAY/?igshid=MDJmNzVkMjY=
