So I had a thought for my first "big" project with my 3D printer to be printing a badass reservoir for my next watercooling build. I'm thinking spiral design or some sort but who knows it might be something I can do in vase mode with a stupid amount of volume. Anyways, I have some basic questions before I start tackling the later ones. 1. How do I go about ensuring a watertight print? 2. How can I either print or attach G1/4 threads to the reservoir safely and securely? 3. Should I print it in PETG or would PLA work? I haven't bothered to look up what coolant would do to the different material types but knowing that the rest of the tubing will be PETG I assume that should be safe but I would have to order that AND learn to print with it. I suppose I would need to order filament regardless because I'm picturing printing this in either white or clear so I can backlight it to show the coolant from within.
