I’ve tried to write a check-list (feel free to comment and make suggestions!) of all the different parts I want to make… and it is pretty big.

Big and incomplete too. I can’t decide on what valve and elements to add to the set and which designs, especially for the 10cm and 30cm pipes.

At least I got more bends done I suppose? These, with the short turn ones I’ve already done for the large pipes SHOULD be everything you realistically need, as far as bent pipes go.

I also don’t know If I want to have flanges on the valves. Not having any means that you can re-use some of the valve parts across pipe sizes, just add the proper flange set to it. But it is less practical, and might end up bloating the LI.
