Filter Media Cups- Trigger Sump

[BirdGuy21]

I am looking to buy three filter media cups that will fit in a Trigger CR 44 sump. I've searched around but can't find any that are a for sure fit. Does anyone know of anywhere to purchase these or anyone who offers a 3D printed option?

Could 3D print something but would need photos and measurements and maybe a sketch of what it is you are looking for
