About this 3D model

Summary 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 = Print Settings Printer: Creality Ender 3 Rafts: No Supports: Yes Resolution: 0.6mm Infill: 10 Gyroid Filament: Generic PLA Red
