Im really trying to see if someone is capable of making me a 4 inch diameter by 6 inch in length aquarium filter cup design that is in 2 pieces that are threaded so they can be screwed together I attached a photo of the space i have to work with. The cups in the photo I made are 4 inch diameter by 4 inch in length and the lip on the top are a little frail... any help or advice will be greatly appreciated. Im new to 3D printing and am fine tuning everything before i start learning how to use a CAD program thanks in advance
