About this 3D model
Filter cartridge that can be filled with carbon pellets and inserted into the Elegoo USB filter. Designed with similar dimensions to the included filter cartridge so slide should be a good fit. I've included the model here if anyone wants to tweak https://cad.onshape.com/documents/95422b2a2349fa746ab08162/w/1c489417e20a287ad9f57e63/e/567744fa1ad9defecf17f24f
